Consider the following hypotheses:

H0: μ = 120
HA: μ ≠ 120

The population is normally distributed with a population standard deviation of 46. Use Table 1.

a.
Use a 5% level of significance to determine the critical value(s) of the test. (Round your answer to 2 decimal places.)

  Critical value(s) ±   

b-1.
Calculate the value of the test statistic with  = 132 and n = 50. (Round intermediate calculations to 4 decimal places. Round your answer to 2 decimal places.)

  Test statistic   

b-2. What is the conclusion at α = 0.05?       Reject H0 since the value of the test statistic is greater than the critical value. Reject H0 since the value of the test statistic is smaller than the critical value. Do not reject H0 since the value of the test statistic is greater than the critical value. Do not reject H0 since the value of the test statistic is smaller than the critical value.

c.
Use a 10% level of significance to determine the critical value(s) of the test. (Round your answer to 2 decimal places.)

  Critical value(s) ±   

d-1.
Calculate the value of the test statistic with  = 108 and n = 50. (Negative value should be indicated by a minus sign. Round intermediate calculations to 4 decimal places. Round your answer to 2 decimal places.)

  Test statistic   


d-2. What is the conclusion at α = 0.10?       Reject H0 since the value of the test statistic is not less than the negative critical value. Reject H0 since the value of the test statistic is less than the negative critical value. Do not reject H0 since the value of the test statistic is not less than the negative critical value. Do not reject H0 since the value of the test statistic is less than the negative critical value.  6.      
In order to conduct a hypothesis test of the population mean, a random sample of 24 observations is drawn from a normally distributed population. The resulting mean and the standard deviation are calculated as 4.8 and 0.8, respectively. Use Table 2.

Use the p-value approach to conduct the following tests at α = 0.05.

H0: μ ≤ 4.5 against HA: μ > 4.5

      Reject H0 since the p-value is less than α. Reject H0 since the p-value is greater than α. Do not reject H0 since the p-value is less than α. Do not reject H0 since the p-value is greater than α.
In order to estimate the mean 30-year fixed mortgage rate for a home loan in the United States, a random sample of 28 recent loans is taken. The average calculated from this sample is 5.25%. It can be assumed that 30-year fixed mortgage rates are normally distributed with a standard deviation of 0.50%. Compute 90% and 99% confidence intervals for the population mean 30-year fixed mortgage rate. Use Table 1.(Round intermediate calculations to 4 decimal places, "z" value and final answers to 2 decimal places. Enter your answers as percentages, not decimals.)

Confidence Level Confidence Interval 90%  %  to  %  99%  %  to  %  8.      
An article in the National Geographic News (“U.S. Racking Up Huge Sleep Debt,” February 24, 2005) argues that Americans are increasingly skimping on their sleep. A researcher in a small Midwestern town wants to estimate the mean weekday sleep time of its adult residents. He takes a random sample of 80 adult residents and records their weekday mean sleep time as 6.4 hours. Assume that the population standard deviation is fairly stable at 1.8 hours. Use Table 1.

a.
Calculate a 95% confidence interval for the population mean weekday sleep time of all adult residents of this Midwestern town. (Round intermediate calculations to 4 decimal places, "z" value and final answers to 2 decimal places.)

  Confidence interval to   

b.
Can we conclude with 95% confidence that the mean sleep time of all adult residents in this Midwestern town is not 7 hours?
      Yes, since the confidence interval contains the value 7. Yes, since the confidence interval does not contain the value 7. No, since the confidence interval contains the value 7. No, since the confidence interval does not contain the value 7.  9.

Need help in Application Project

Q:

Necessary Background
The following project uses the game of Guess Your Card. This is a game in which each playerdraws (without looking) three cards. Each card has a number between 1 and 9 on it. The playersthen place their cards on their heads so that everyone but themselves can see the cards.The object of the game is to guess what cards you have. The first person to do this correctly,wins.During the play, each player, in turn, draws a question at random from a stack of questions.The player then answers the question based on the cards that they see (not their own cards, whichthey cannot see).An Example
Andy has the cards 6 6 7
Belle has the cards 3 6 7
Carol has the cards 1 1 9
Dan has the cards 3 4 8
Andy draws the question card, “How many 7s do you see?” He answers, “one,” because hecannot see the 7 on his own head; he sees only the 7 on Belle’s head.Next Belle draws the question card, “Of the four even numbers, how many different even numbersdo you see? She answers “three,” because she sees the 4, 6, and 8 on Andy and Dan’s head. Fromthis, Dan can conclude he has two even cards, since he can only see a 6 and Belle sees two more.
The Project’s Situation
You are playing Guess Your Card with three other players. Here is what you see:
Andy has the cards 1 3 7
Belle has the cards 3 4 7
Carol has the cards 4 6 8
Andy draws the question card, “Do you see two or more players whose cards sum to the samevalue?”
 He answers, “Yes.”Next Belle draws the question card, “Of the five odd numbers, how many different odd numbersdo you see?
 She answers “All of them.”Andy suddenly speaks up. ”I know what I have,” he says. ”I have a one, a three, and a seven.”The QuestionWhat cards do you have?
In answering this question, you must write a neat and professional report. You need to briefly
summarize the salient facts of the problem, explain your strategy for solving the problem, explain
why your strategy will work, execute your strategy, show your mathematical working, draw conclusions
from your working, and finally present your answer with a brief summery of why it is your
conclusion.
Remember, your strategy is to use more than logic. What kind of logic will you use?
Writing Assignments
Directions
Writing assignments are to be typed solutions. The best way to envision how these papers
are to be constructed is to imagine that you have been hired to answer the questions given in the
assignments. When problem analysts submit their reports to their clients, they do more than simply
answer the question. The document is broken into four parts; in order:
The Problem: This is a statement of the problem that you have been asked to solve. It is
stated in a single, simple sentence. Any necessary and significant details should follow. Think of
this as being the question you have ultimately been hired to answer. Be sure to use your own words.
Remember that your audience is aware of what question they hired you to answer, however, it most
likely has been a fair amount of time and they are busy people. You want to be clear, concise,
include everything important, but don’t waste the readers time.
The Approach: What strategy will you use to solve this problem? This is tougher to convey in
a single, simple sentence, and sometimes even a single paragraph. However, you can almost always
begin with a statement saying the method that you used. Follow this with an overview of how you
put the facts together with the technique to get an answer.
This is not a section of mathematical calculations. No calculations are seen here at all. In fact,
this section must be written in future tense, as though you have not already done this work. You
are writing as though you are explaining a proposed method of solving the problem, not from the
standpoint of someone who has already done the work.
Remember, this section is about how you will solve the problem. It cannot seem as though
you have already drawn a conclusion. It should not read like you have already done the work.
Otherwise, you could be accused of bias; if the analyst profits from a particular answer, then they
will choose a method that will lead to this answer. To avoid this perception, you need to maintain
a tone and style of detachment. You do not care which answer you receive for the question, only
what the answer is, whatever it is. To help ensure this tone, you need to include the different
conditions under which you will draw your different possible conclusions. Ultimately, all these
projects involving calculating some value(s) and then choosing a course of action based on this.
Explain what range of values of your possible solution(s) correspond with which courses of action.
Conclusion: Here you start by stating the recommended course of action. You follow this with
a summary of the reasons for your recommendation. This section is the most important section.
You must be sure you are conveying everything needed without boring the reader with extraneous
information. Your reasoning needs to tie back into the explanation you gave in The Approach
regarding how you would choose the course of action.
Solution Details: Only now do you include the mathematics. You must include not just the
calculations, but also a brief explanation of each calculation.
You should also consider the following questions in writing any report.
1. Neatness and professionalism of presentation:
• Is your text legible, on white paper with black ink?
• Are your pages stapled, without frilly edges, of regular size (81
2 × 11), and uncrumpled?
• Have you used sentences and paragraphs appropriately?
• Is your text reasonably free of typos and spelling mistakes?
• Does your presentation include an opening statement describing what you intend to
present and a conclusion wrapping up the presentation?
2. Appropriateness and explanation of problem solving strategy: 10 points
• If preformed correctly, will your strategy solve the problem?
• Is it clear to the reader why your steps will solve the problem?
• Are the steps of your strategy in a logical order?
• Are there any redundant or unnecessary steps?
3. Implementation of strategy:
• Did you follow the strategy you outlined?
• Did you preform the steps of your strategy correctly?
4. Use of appropriate mathematical notation and language:
• Are you using mathematical language as opposed to common, less precise language?
• Are you using mathematical language according to its definition as opposed to a less
precise manner?
• Are you using the symbols of mathematics correctly?
5. Presentation of the results presented in the context of the question:
• Is the question you are asked, answered?
• Is it clear from your presentation (both in the opening and closing) what the question
you are answering is?

• Does your answer include a brief summery of why you decided on this answer?

The MorTex Company Sum Solution


The MorTex Company assembles garments entirely by hand even though a textile machine exists that can assemble garments faster than a human can. Workers cost $50 per day, and each additional laborer can produce 200 more units per day (i.e., marginal product is constant and equal to 200). Installation of the first textile machine on the assembly line will increase output by 1,800 units daily. Currently the firm assembles 5,400 units per day.

The financial analysis department at MorTex estimates that the price of a textile machine is $600 per day. Can management reduce the cost of assembling 5,400 units per day by purchasing a textile machine and using less labor? Why or why not? The Textile Workers of America is planning to strike for higher wages. Management predicts that if the strike is successful, the cost of labor will increase to $100 per day. If the strike is successful, how would this affect the decision in part a to purchase a textile machine? Explain.

Week 4 Simulation Background Information

Q:
In this exercise, you will be observing a mediation of a dispute under the Americans with Disabilities Act.  The information below is provided to familiarize you with some of the major legal issues presented. After you read the information below and observe the simulation, you should complete the assignment.  You will answer the question posed and post your answer to the Dropbox underWeek 4: Simulation. 
Background Information:
Congress passed the Americans with Disabilities Act (ADA) in 1990. The purpose of the ADA is to prevent discrimination against people with disabilities in the workforce -- as well as in most businesses and other places open to the public -- by requiring that "reasonable accommodations" be made for many types of disability.
Prohibited discrimination includes classifying disabled employees so that their job opportunities are more limited than the job opportunities of non-disabled employees, or setting standards that make it harder for disabled employees to compete. 
You can review the Act (ADA of 1990, Titles I and V) in detail at the website of The U.S. Equal Employment Opportunity Commission . You should skim the Act to understand the definitions that apply and use these definitions to determine if the mediator applies the correct standards.  Remember that the law shapes the propriety of the agreement reached in the mediation.
As the statute points out, the ADA only applies to persons who meet the definition of "disabled" under the Act.  If an employee or other person covered under the Act has impairment that substantially limits his or her ability to perform a “major life activity,” the person is considered disabled under the ADA. 
Although the determination of whether a worker is disabled is made on a case-by-case basis, common examples of disabilities include confinement to a wheelchair, blindness, deafness, a learning disability, and certain kinds of mental illness. For example, if an employee is hard of hearing, but has normal hearing when wearing a hearing aid, this employee is not considered disabled under the ADA. 
Assuming an employee is disabled under the ADA, an employer has a responsibility to make "reasonable accommodations" for the employee's disability.  Generally speaking, a reasonable accommodation allows a disabled employee to perform a job in the same manner as a non-disabled employee.
While the ADA applies to all disabled employees of qualified employers, it does allow employers limited latitude in refusing to accommodate the disabled in the workplace.  An employer may also refuse to accommodate a disabled person if the accommodation that would allow him or her to perform the job is not "reasonable."
Another justification for refusal would be undue hardship if the accommodation would be extremely difficult or expensive. As defined in the Act [Title I, Section 101(10)]:
(A) In general. - The term “undue hardship'' means an action requiring significant difficulty or expense, when considered in light of the factors set forth in subparagraph
(B)Factors to be considered. - In determining whether an accommodation would impose an undue hardship on a covered entity, factors to be considered include-
     (i) the nature and cost of the accommodation needed under this chapter;
     (ii) the overall financial resources of the facility or facilities involved in the provision of the reasonable accommodation; the number of persons employed at such facility; the effect on expenses and resources, or the impact otherwise of such accommodation upon the operation of the facility;
     (iii) the overall financial resources of the covered entity; the overall size of the business of a covered entity with respect to the number of its employees; the number, type, and location of its facilities; and
     (iv) the type of operation or operations of the covered entity, including the composition, structure, and functions of the workforce of such entity; the geographic separateness, administrative, or fiscal relationship of the facility or facilities in question to the covered entity.
Now, please watch the ADA simulation and don’t forget to complete the assignment given below the simulation. The assignment is to answer the question at the bottom of this page using the information provided in this simulation.

Assignment:
A second year student at State College is majoring in music and uses a wheelchair to get around. Since he has been at State College he has been unable to use the music building on campus because it has no ramps and really tall steps. He has had others carry him into the building at times to use the facilities but considers this to be a hassle and detrimental to his music studies. State college counters that due to the age (200 years) and historical architectural significance of the building it would cost over $1 million to add ramps to make the building ADA compliant.  What do you think?
