Stats
2. Number of Jobs The U.S. Bureau of Labor and Statistics reported that a person between the ages of 18 and 34 has had an average of 9.2 jobs. To see if this average is correct, a researcher selected a sample of 8 workers between the ages of 18 and 34 and asked how many different places they had worked. The results were as follows:
8 12 15 6 1 9 13 2 At α = 0.05 can it be concluded that the mean is 9.2? Use the P-value method. Give one reason why the respondents might not have given the exact number of jobs that they have worked. a. State the hypotheses and identify the claim. b. Compute the test value. c. Find the P-value. d. Make the decision. e. Summarize the results. |
