Test the indicated claim about the means of two populations. Assume that the two samples are independent and that they have been randomly selected.


A researcher wishes to determine whether people with high blood pressure can reduce their blood pressure by following a particular diet. Use the sample data below to test the claim that the treatment population mean μ1 is smaller than the control population mean μ2. Test the claim using a significance level of 0.01.

Treatment Group

n1 = 85

x1 = 189.1

s1 = 38.7

Control Group

n2 = 75

x2 = 203.7

s2 = 39.2
