Random samples of resting heart rates are taken from two groups. Population 1 exercises regulary, and Population 2 does not. The data from these two samples is given below. Population 1:69, 65, 66, 71, 67, 69, 65 Population 2: 76, 76, 69, 77, 70, 69, 60, 68 Is there evidence, at an a-0.035 level of significance, to conclude that there those who exercise regularty have lower resting heart rates? (Assume that the population variancen that the population distributions are normal) Cary out an appropriate hypothesis test, ing in the infomation requested. A. The value of the test statistic: Note: For the next part, your answer shoud une interval notation An answer of the fom (-o, a) is expresed (inty, al an anwer of the form (,0) is expressed ntyl, andi the form (-o0, a) U(, ) is expressed (-inty, au, inty Hint For example, note that a rejection region of "reject Ha ift>," can be expressed as reject H, t belongs to the interval (ta o0). B. The rejection region for the test statistic: C. Run the analysis on Mintab to obtain the p-value
