Question:

Consider the following competing hypotheses and accompanying sample data drawn independently from normally distributed populations.

Họ: H1 - 42 = 0 HẠ: 41 - 42 +0 X1 = 57 X2 = 63 01 = 11.5 02 = 15.2 ni = 20 n2 = 20

a. Using the p -value approach, test whether the population means differ at the 5% significance level.

b. Repeat the hypothesis test using the critical value approach.
