1. Suppose a sample of eight 35- to 39-year-old nonpregnant, premenopausal OC users who work in a company are identified who have mean systolic blood pressure of 132.86 mm Hg and sample standard deviation of 15.34 mm Hg. A sample of twenty-one 35- to 39- year-old nonpregnant, premenopausal non-OC users are similarly identified who have mean systolic blood pressure of 127.44 mm Hg and sample standard deviation of 18.23 mm Hg. What can be said about the underlying mean difference in blood pressure between the two groups?
