Consider the following hypothesis statement using alphaαequals=0.10 and data from two independent samples. Assume the population variances are equal and the populations are normally distributed. Complete parts below.

H0: μ1−μ2 = 0 x overbar 1 = 14.8 x overbar 2 = 13.0

H1: μ1−μ2 ≠ 0 s1= 2.8 s2 = 3.2

n1 = 21 n2 = 15

a.) what is the test statistic?

b.) the critical values are

c.) what is the p value?
