Exhibit 9-41 A random sample of 9 students selected from the student body of a high school had an average age of 14 years. We want to determine if the average age of all the students at the high school is significantly different from 13. Assume the distribution of the population of ages is normal with a standard deviation of 1 year. Refer to Exhibit 9-41. What is the p-value for this test? 0.00135 0.0027 1.96 0.0045
