Extracted text: Problem 6 – Assume that the population is approximately distributed. The Department of Labor and Employment reported that a person between the ages of 20 and 40 has had an average of 9.2 jobs. To see if this average is correct, a statistician selected a sample 8 employees between the ages of 20 and 40 and asked how many different companies they had been employed. The results are shown below: 8 12 15 6 1 9 13 2 At a = 0.05, can it be concluded that the mean is 9.2? Use the P-value method. Also, give one reason why the number of respondents might not have given the exact number of jobs that they have been employed.
