1. The Citizens Banking Company is studying the number of times the ATM located in a Safeway Supermarket at the foot of Market Street is used per day. It measured the numbers of times the machine was used each day over each of the last 30 days and provided this data to you. If the machine is used on average 25 times per day, it will remain in the Safeway; otherwise it will be removed. What statistical test would you use to produce the data necessary to make this decision? Explain how you would do this. (You do not have to compute the statistics.)

2. A survey of undergraduate students in the School of Business at Northern University revealed the following regarding the gender and majors of the students: Accounting Management Finance Total Male 100 150 50 300 Female 100 50 50 200 Total 200 200 100 500

a. For each student, you also measured Satisfaction with the School of Business on a Likert scale where 1 = extremely dissatisfied, 5 = extremely satisfied. What statistical test would you use to determine if there are differences in satisfaction among students of different majors? Explain what that test tells you, and how you would interpret it. Be sure to identify your variables. (You do not have to compute the statistics.)

b. What statistical test would you use to determine if there is an interaction between gender and major on the degree of satisfaction among students (e.g., Male Accounting majors have the most satisfaction, followed by Management and Finance.but Female Finance majors have the most satisfaction, followed by Management and Accounting)? Explain what that test tells you and how you would interpret it, including how you would recognize such an interaction. Be sure to identify your variables. (You do not have to compute the statistics.)

c. What statistical test would you use to determine if the observed distribution of women across majors is significantly different from the distribution of men across majors (i.e., there are fewer women in the management major). Explain what that test tells you and how you would interpret it. Be sure to identify your variables. (You do not have to compute the statistics.)

3. The number of passengers on the Carnival Sensation during one-week cruises in the Caribbean follows the normal distribution. The mean number of passengers per cruise is 1,820 and the standard deviation is 120.

a. What percent of the cruises will have between 1,580 and 1,940 passengers?

b. What percent of the cruises will have 1,940 passengers or more?

c. What percent of the cruises will have 1,580 or fewer passengers?

4. Interpret the value 0.3 in the following conditions. (If necessary, assume the size of the sample is 50):

a. (1 point) p = 0.3

b. (1 point) r = 0.3

c. (2 points) R2 = 0.3

d. (2 points) Cronbachs = 0.3

e. (3 points) kurtosis = 0.3

f. (3 points) Durbin Watson statistic d = 0.3

g. (3 points) For Shapiro-Wilks W, p = 0.3

5. I want to know if putting my company name at the top of my web page or the bottom of my web page produces more click-throughs to the next level of my web page. I set up an experiment with 2 groups. Group one sees the web page with my name at the top. Group two sees the web page with my name at the bottom. I measure the percent of people who click through to the next level of my website. Identify the independent variable(s), dependent variable(s), their levels of measurement, and what kind of test is appropriate in this study.

Independent Variables(s) =

Level of measurement =

Dependent Variable(s) =
