A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure, measured in mm Hg, by following a particular diet. Use a significance level of 0.05 to test the claim that the treatment group is from a population with a smaller mean than the control group. Assume unequal variances between the two populations.

	Treatment	Control
n	35	28
x	189.1	203.7
sx	38.7	39.2
