The times to failure of certain electronic componentsin accelerate environment tests are 15, 28, 3, 12, 42, 19,20, 2, 25, 30, 62, 12, 18, 16, 44, 65, 33, 51, 4, and 28 minutes. Looking upon these data as a random sample froman exponential population, use the results of Exercise 21and Theorem 2 to test the null hypothesis ? = 15 minutes against the alternative hypothesis ? Z 15 minutes atthe 0.05 level of significance. (Use ln 1.763 = 0.570.)
