Random samples of resting heart rates are taken from two groups. Population 1 exercises regularly, and Population 2 does not. The data from these amples is given below: Population 1: 66, 71, 69, 73, 66, 66, 65 Population 2: 70, 68, 77, 78, 75, 77, 71, 70 s there evidence, at an a = 0.02 level of significance, to conclude that there those who exercise regularly have lower resting heart rates? (Use the conservative method for computing degrees of freedom). Carry out an appropriate hypothesis test, filling in the information requested. A. The value of the standardized test statistic: B. The p-value is C. Your decision for the hypothesis test: A. Do Not Reject H₁. OB. Reject Ho. OC. Do Not Reject Ho.
