We are testing H₀: µ ≤ 42; versus H_A: µ 42. When = 45, s = 1.2, and n = 15, at α = .01 we do not reject the null hypothesis. Assume that the population from which the sample is selected is normally distributed.

We are testing H₀: µ ≤ 42; versus H_A: µ > 42. When = 45, s = 1.2, and n = 15, at α = .01 we do not reject the null hypothesis. Assume that the population from which the sample is selected is normally distributed.

t = (45 − 42/(1.2/) = 3/.3 = 10 t_.01,14 = 2.624 10 > 2.624; reject H₀
