Question

4. A reporter from the Sacramento Bee claims that more than 15% of California workers say it is likely they will quit working this year. In a simple random sample of 240 California workers, 19% said it is likely they will quit working this year. At the significance level of 10%, is there enough statistical evidence to support the report's claim? (11 points) Requirements: 1. 2. 3. Step 1: State the hypothesis: Ho: Ha: Tail Step 2: Draw your distribution and find critical number(s) Step 3: Compute the test statistics. Step 4: Make a Decision: Step 5: Summarize the result: (Restate the level of significance and discuss the claim) 5. A career counselor at the college claims that the mean annual salary of entry-level engineers in Roseville and Sacramento is the same. The mean annual salary of a simple random sample of 54 entry-level engineers in Roseville gives a mean of $78,350. Assume the population standard deviation is $1231. The mean annual salary of a simple random sample of 36 entry-level engineers in Sacramento gives a mean of $79,451. Assume the population standard deviation is $1536. Assume the samples were taken independently. At a level of significance of 10% is there enough evidence to support the counselor's claim? (11 points) Requirements: 1. 2. 3. 4.
