(Ch10.7) True or False? Based on a random sample of 13 tire changes (n1), the mean time to change a tire on a Boeing 777 has a mean of 59.5 minutes with a standard deviation of 7.4 minutes. For 10 tire changes (n2) on a Boeing 787, the mean time was 64.3 minutes with a standard deviation of 13.2 minutes. In testing equal variances in a "two-tailed" F-test at α=0.1, we should reject the null hypothesis of equal population variances.
