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: 67, 63, 70, 72, 71, 67, 68 Population 2: 76, 78, 79, 77, 78, 71, 69, 72 x¯1 = s1 = x¯2 = s2 = To help see if there is enough evidence to conclude that those who exercise regularly have lower resting heart rates, fill in the information requested. A. The value of the test statistic: B. The degree of freedom of the distribution: C. The approximate range of values for the p-value: < p-value <
