  1. The average price of a gallon of unleaded regular gasoline was reported to be $3.44 in northern Kentucky. Use this price as the population mean, and assume the population standard deviation is $0.30.
    1. What is the probability that the mean price for a sample of 50 service stations is within ±$.06 of the population mean?
    2. What is the probability that the mean price for a sample of 100 service stations is within ±$.06 of the population mean?

  1. The Wall Street Journal reported that automobile crashes cost the United States $162 billion annually. The average cost per person for crashes in the Tampa, Florida, area was reported to be $1900. Suppose this average cost was based on a sample of 50 persons who had been involved in car crashes and that the population standard deviation is known to be $500. What is the 90% confidence interval of the average cost per person for crashes in Tampa? What would you recommend if the study required a margin of error of $150 or less?

Consider two tests that could be used to evaluate a university’s effectiveness at teaching critical thinking and communication skills to undergraduates. The first test is a multiple-choice test with questions on reading comprehension, language, and math, similar to the SAT in the United States. The second test provides the students with a single real world case involving practical issues and data, including quantitative data, from several sources. The product that students produce for the second test is a memo, which must suggest a particular response to the case and support the decision with evidence and analysis. The second test is graded using specific criteria on critical thinking and communication (a rubric).

Discus the validity of each test for assessing the level of critical thinking and communication skills of students. Compare and contrast the two tests in terms of validity.

Discuss the reliability of each test for assessing the level of critical thinking and communication skills of students. Compare and contrast the two tests in terms of reliability.

The Zagat Restaurant Survey provides food, decor, and service ratings for some of the top restaurants across the United States. For 18 restaurants located in a certain city, the average price of a dinner, including one drink and tip, was $48.60. You are leaving on a business trip to this city and will eat dinner at three of these restaurants. Your company will reimburse you for a maximum of $50 per dinner. Business associates familiar with these restaurants have told you that the meal cost at one-third of these restaurants will exceed $50. Suppose that you randomly select three of these restaurants for dinner. (Round your answers to four decimal places.)

(a)

What is the probability that none of the meals will exceed the cost covered by your company?

(b)

What is the probability that one of the meals will exceed the cost covered by your company?

(c)

What is the probability that two of the meals will exceed the cost covered by your company?

(d)

What is the probability that all three of the meals will exceed the cost covered by your company?

1. Define compensating differential and give original examples (not already included in the book or power points) of different jobs that earn higher wages and some that earn lower wages because of compensating differentials.

2. Go to the Education Pays (Links to an external site.) page on the Bureau of Labor Statistics website. Compare and contrast the different levels of education in relation to average wage and unemployment rate.

3. Explain the benefits of higher education in terms of the unemployment rate and average salary figures in the United States.

4. How does this reflect on your own decision to invest in your human capital?

5. Also, go to the BLS Occupational Outlook Handbook (Links to an external site.) and look up two careers that you may be interested in pursuing.

6. Does the information given about these careers match your expectations?

7. Is there expected growth of jobs in these careers? How might it affect your likelihood of finding a job after graduation?

The Human Toxome Project (HTP) is working to understand the scope of industrial pollution in the human body. Industrial chemicals may enter the body through pollution or as ingredients in consumer products.

In October 2008, the scientists at HTP tested core blood samples for 35 newborn infants in the United States. The cord blood of the "In utero/newborn" group was tested for 430 industrial compounds, pollutants, and other chemicals, including chemicals linked to brain and nervous system toxicity, immune system toxicity, and reproductive toxicity, and fertility problems. There are health concerns about the effects of some chemicals on the brain and nervous system. Upon calculation of the sample, the mean of the amount of the chemical found in the infant's blood is equal to with sample standard deviation equal to.

Construct the 90% confidence interval by

- Clearly explain what model was used and why

- Clearly show your process, if using calculator explain what you did.

- Explain the meaning of the 90% confidence interval in the context of the problem.

In the following situations, decide whether you would use a personal interview, telephone survey, or self-administered questionnaire. Give you reasons. a. A survey of the residents of a new subdivision on why they happened to select that area in which to live. You also wish to secure some information about what they like and don not like about life in the subdivision. b. A poll of students at Metro University on their preferences among three candidates who are running for president of the student government. c. A survey of 58 wholesale grocery companies scattered over the eastern United States, on their personnel management policies for warehouse personnel. d. A survey of financial offers of the Fortune 500 Corporations to learn their predictions for the economic outlook in their industries in the next year. e. A study of applicant requirements, job tasks, and performance expectations as part of a job analysis of student work-study jobs on a college campus of 2,000 students, where 1,500 are involved in the work-study program.
