Suppose a company surveyed the work preferences and attitudes of 1,006 working adults spread over three generations: baby boomers, Generation X, and millennials. In one question. individuals were asked if they would leave their current job to make more money at anotherjob. The sample data are summarized in the following table. Conduct a test of independence to determine whether interest in leaving a current job for more money is independent of employee generation. State the null and alternative hypotheses. 0 Ho: Interest in leaving job for more money is not mutually exclusive of the employee generation. Ha: Interest in leaving job for more money is mutually exclusive of the employee generation. 0 H0: Interest in leaving job for more money is not independent of the employee generation. Ha: Interest in leaving job for more money is independent of the employee generation. 0 Ho: Interest in leaving job for more money is independent of the employee generation. Ha: Interest in leaving job for more money is not independent of the employee generation. 0 Ho: Interest in leaving job for more money is mutually exclusive of the employee generation. Ha: Interest in leaving job for more money is not mutually exclusive of the employee generation. Find the value of the test statistic. (Round your answer to two decimal places.) :I What is the pvalue? (Round your answer to four decimal places.) E Using a 0.05 level of signicance, what is your conclusion? 0 Reject Ho.

We conclude that interest in leaving a job for more money is not independent of the employee generation. The Wall Street Journal's Shareholder Scoreboard tracks the performance of 1,000 major U.S. companies. The performance of each company is rated based on the annual total return, including stock price changes and the re investment of dividends. Ratings are assigned by dividing all 1,000 companies into five groups from A (top 20%), B (next 20%), to E (bottom 20%). Shown here are the one-year ratings for a sample of 60 of the largest companies. A 1; c 11': 5 3 15 20 ' 12 Do the largest companies differ in performance from the performance of the 1,000 companies in the Shareholder Scoreboard? Use a = 0.05. State the null and alternative hypotheses. O Ho: The proportions of the largest companies compared to the 1,000 companies are the same for the majority of the five groups. Ha: The proportions of the largest companies compared to the 1,000 companies are different for the majority of the five groups. 0 HO: The largest companies do not differ in performance from the 1,000 companies.

During the first 13 weeks of the television season, the Saturday evening 8 p.m. to 9 p.m. audience proportions were recorded as ABC 31%, CBS 26%, NBC 27%, and independents 16%. A sample of 300 homes two weeks after a Saturday night schedule revision yielded the following viewing audience data: ABC 97 homes, CBS 68 homes, NBC 91 homes, and independents 44 homes. Test with a = 0.05 to determine whether the viewing audience proportions changed. State the null and alternative hypotheses.
