Test the claim about the means of two populations. Do not assume that the population standard deviations are equal. A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure by following a particular diet. Use a significance level of 0.01 to test the claim that the treatment group is from a population with a smaller mean than the control group.

Treatment Group Control Group

n1 = 101 n2 = 105

?̅1 = 120.5 ?̅2 = 149.3

s1 = 17.4 s2 = 30.2
