Question

We are testing H₀: µ ? 42;versus H_A: µ > 42.When

\bar { Y } = 45

s = 1.2,and n = 15,at ? = .01 we do not reject the null hypothesis.(Assume that the population from which the sample is selected is normally distributed. )

Since we do not reject the null hypothesis, this means we cannot conclude that µ ≤ 42. Therefore, we cannot accept the alternative hypothesis µ > 42. Hence, the claim H_A: µ > 42 is false, and the correct hypothesis should be H₀: µ ≤ 42.
