Test H0: μ1 % μ2; H1: μ1 > μ2 at α = 0.05, when 1 = 75, 2 = 72, s1 = 3.3, s2 = 2.1, n1= 6, n2= 6. Assume equal variances. Indicate which test you are performing; show the hypotheses, the test statistic and the critical values and mention whether one-tailed or two-tailed.
There is sufficient evidence to conclude that the claim of this hypothetical weight loss programs has strong support from this sample.
