Random samples of resting heart rates are taken from two
groups. Population 1 exercises regularly, and Population 2 does
not. The data from these two samples is given below:
Population 1: 59, 69, 63, 59, 69, 68, 65
Population 2: 73, 69, 71, 76, 75, 68, 71, 69
Is there evidence, at an ?=0.05

level of significance, to conclude that there those who
exercise regularly have lower resting heart rates? (Assume that the
population variances are equal.) Carry out an appropriate
hypothesis test, filling in the information requested.
