Suppose you want to test the claim that μ1 < μ2. Two samples are random, independent, and come from populations that are normally distributed. The sample statistics are given below. Assume that = . At a level of significance of when should you reject H0?
n1 = 15 n2 = 15
1 = 27.37 2 = 29.92
s1 = 2.9 s2 = 2.8
A. if the standardized test statistic is less than -1.313.Reject H
B.Reject H0 if the standardized test statistic is less than -1.701.
C. Reject H0 if the standardized test statistic is less than -2.467.
D. Reject H0 if the standardized test statistic is less than -0.683.
