You are given the following null and alternative hypotheses: H0: m1 m2 HA: m1 6 m2

You are given the following null and alternative hypotheses:

H0: m1 Ú m2 HA: m1 6 m2 together with the following sample information:

Sample 1 Sample 2 n1 = 14 n2 = 18 x1 = 565 x2 = 578 s1 = 28.9 s2 = 26.3

a. Assuming that the populations are normally distributed with equal variances, test at the 0.10 level of significance whether you would reject the null hypothesis based on the sample information.

Use the test statistic approach.

b. Assuming that the populations are normally distributed with equal variances, test at the 0.05 level of significance whether you would reject the null hypothesis based on the sample information.

Use the test statistic approach.
