A university financial aid office polled a random sample of 528 528 male undergraduate students and 651 651 female undergraduate students. Each of the students was asked whether or not they were employed during the previous summer. 295 295 of the male students and 463 463 of the female students said that they had worked during the previous summer. Give a 80% 80% confidence interval for the difference between the proportions of male and female students who were employed during the summer.

Step 2 of 4 :

Find the critical value that should be used in constructing the confidence interval.

Students of a large university spend an average of $6 a day on lunch. The standard deviation of the expenditure is $2. A simple random sample of 81 students is taken. 1. What is the probability that the sample mean will be at least $5.25? 2. What is the probability that the sample mean will be at least $6.50? 3. What is the range of money spent by people who fall within one standard deviation of the mean? 4. Kelsey spent $12 on her lunch today. Explain to her, in terms of the normal distribution curve and standard deviation, why her purchase is not very typical.

Determine the Appropriate Analysis For each of the following scenarios, identify the appropriate analysis.

2. A guidance counselor at a high school wants to be best informed about the universities and colleges that students prefer most frequently. He glances at the institutions attended by last year’s graduates and notes that the three closet colleges appear to have about equal appeal. To test this assumption, he begins asking students who are planning on postsecondary schooling where they will apply. His data are as follows:

The technical institute: 22

The community college: 18

The comprehensive university: 12

• Create a set of use case documents and use case diagrams for a university library borrowing system (Do not worry about catalogue searching etc.)
• The system will record who has borrowed what books. Before someone can borrow a book, he or she must show a valid ID card that is checked to ensure that it is still valid against the student database maintained by the registrar's office.
• The system must also check to ensure that the borrower does not have any overdue books or unpaid fines before he or she can borrow another book.

As a long-term investment, Fair Company purchased 20% of Midlin Company’s 300,000 shares for $360,000 at the beginning of the reporting year of both companies. During the year, Midlin earned net income of $135,000 and distributed cash dividends of $0.25 per share. At year-end, the fair value of the shares is $375,000. 1. Assume no significant influence was acquired. Record the transactions from the purchase through the end of the year, including any adjustment for the investment’s fair value, if appropriate. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)
