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 random sample of 12 workers between the ages of 18 and 34 and asked how many different places they had worked. The results were as follows: 7 10 12 5 1 6 2 2 6 10 7 7 Send data to Excel At a = 0.01, can it be concluded that the mean is 9.2? Use the P-value method. Assume the population is normally distributed. Use a TI-83 Plus/TI-84 Plus calculator.
