Description: Eight middle aged women participated in a study of exercise and health. Each woman’s resting pulse rate (bpm)was taken before and after a two week program of regular exercise with the following resultsSubject Before After1 65

Given: woman’s resting pulse rate (bpm) before and after a two-week program of regular exercise. n=8 α=0.05 Hypothesis: H0:μd=0 H0: The no difference in the pulse rate before and after the program. H1:μd<0 H1: There is a decrease in the pulse rate after the treatment.(Before pulse rate is higher than after pulse rate). The difference table is given below Before After Difference(After-Before ) 65 56 -9 62 58 -4 76 75 -1 75 78 3 81 72 -9 72 65 -7 85 80 -5 78 68 -10 using the excel formula "=AVERAGE(C2:C9)" the mean difference d¯ = -5.25. using the excel formula "=STDEV.S(C2:C9)" the standard deviation of difference sd=4.496 Test statistic t=d¯sdn=-5.254.4968=-3.303 using the excel formula "=1-T.DIST(3.303,7,1)" p-value = 0.0065Decision rule: If the p-value is greater than the significance level, there is no evidence to reject the null hypothesis. If the p-value is lesser than the significance level, the hypothesis is rejected. Conclusion: The p-value (0.0065) is less than the significance (0.05) Thus, the null hypothesis is rejected. There is a decrease in the pulse rate after the treatment. (Before pulse rate is higher than after pulse rate).
