A Deloitte employment survey asked a sample of human resource executives how their company planned to change its workforce over the next 12 months. A categorical response variable showed three options: the company plans to hire and add to the number of employees, the company plans no change in the number of employees, or the company plans to lay off and reduce the number of employees. Another categorical variable indicated if the company was private or public. Sample data for 180 companies are summarized as follows. Employment Plan Company Private Public Add Employees 37 32 No Change 19 34 Lay Off Employees 16 42 1) Conduct a test of independence to determine if the employment plan for the next 12 months is independent of the type of company.

According to the February 2008 Federal Trade Commission report on consumer fraud and identity theft, 23% of all complaints in the U.S. in 2007 were for identity theft. In that year, Alaska had 321 complaints of identity theft out of 1,432 consumers ("Consumer fraud and," 2008). Does this data provide enough evidence to show that Alaska had a different proportion of identity theft than 23%? Test at 5% level.
A study is designed to determine whether or not taking four years of math in high school helps students' acceptance chances at NC State. • At a certain high school 300 students were not permitted to take a fourth year of math and 300 students were required to take a fourth year of math. • In comparing the acceptance rates of the 600 students at NC State it is noted that the average entrance rate for those who took a fourth year of math is higher than those who took three years of math. • Based on this experiment, guidance counselors began recommending a fourth year of math for college bound students. Which of the following is not true?
3) Recent revenue shortfalls in a Midwestern state led to a reduction in the state budget for higher education. To offset the reduction, the largest state university proposed a 25% tuition increase. It was determine that such an increase was needed simply to compensate for the lost support from the state. Separate random samples of 50 freshmen, 50 sophomores, 50 juniors, and 50 seniors from the university were asked whether they were strongly opposed to the increase, given that it was the minimum increase necessary to maintain the university's budget at current levels. Is there evidence to show a difference in opinion between the years? ASSUME THE CONDITIONS FOR INFERENCE ARE SATISFIED 이 Year Freshman Sophomore Junior Senior Total 18 122 29 Strongly Yes opposed?
