Random samples of resting heart rates are taken from two groups. Population 1 exercises regularly, and...

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: 72, 73, 63, 68, 65, 67, 67 Population 2: 69, 70, 74, 68, 68, 76, 73, 74

Is there evidence, at an ?=0.05 α = 0.05 level of significance, to conclude that those who exercise regularly have lower resting heart rates? Carry out an appropriate hypothesis test, filling in the information requested.

A. The value of the test statistic is (enter a positive number):

B. The P-value is (roughly) equal to:

C. Your decision for the hypothesis test: A. Fail Reject ?? H A . B. Reject ?0 H 0 . C. Reject ?? H A . D. Fail to Reject ?0 H 0 .
