Assume that you have a sample of n1 = 7, with the sample mean XBar X1 = 44, and a sample standard deviation of S1 = 5, and you have an independent sample of n2 = 14 from another population with a sample mean XBar X2 = 36 and sample standard deviation S2 = 6. a. Using the level of significance α = 0.01, what is the critical value for a one tail test of the hypothesis H0:µ1 ≤ µ2 against the alternative H1:µ1 > µ2? b. What is your statistical decision?
