4. 3,539 participants attended the seventh examination of the Offspring in the Fram- ingham Heart Study. Assess whether there is a statistically significant difference in mean systolic blood pressures between men and women using a 5% level of signifi- cance. Data on systolic blood pressures between men are: nm = 1,623,X,m = 128.2, %3D and sm = 17.5 and for women are nf = 1,911,X = 126.5, and sf = = 20.1. Note %3D that nm, Xm, and sm denote sample size, mean, and standard deviation respectively for male. Also nf, X, and S denote sample size, mean, and standard deviation respectively for female.
