You wish to test the following claim (Hi) at a significance level of a = 0.02. H: = 42 H: > M2 You believe both populations are normally distributed, but you do not know the standard deviations for either. However, you also have no reason to believe the variances of the two populations are not equal. You obtain a sample of size ni = 26 with a mean of M1 = 68.6 and a standard deviation of SD = 14.7...
