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: 66, 69, 71, 65, 69, 73, 65

Population 2: 76, 75, 76, 71, 69, 78, 71, 75

Is there evidence, at an a=0.02 level of significance, to conclude that there those who exercise regularly have lower resting heart rates? Carry out an appropriate hypothesis test, filling in the information requested.
