Astudy shows that running increases the percent resting metabolic rate (rmr) in older women. the average rmr of 30 elderly women runners was 32.4% higher than the average rmr of 30 sedentary elderly women, and the standard deviations were reported to be 10.6% and 10.2%, respectively. was there a significance increase in rmr of the women runners over the sedentary women? assume the populations to be approximately normally distributed with equal variances. use a p-value in the conclusion. let sample 1 be the women runners and let sample 2 be the sedentary women. state the null and alternative hypotheses. h_0: mu_1 - mu_2 = 0 h_1: mu_1 - mu_2 > 0 determine the test statistic. t =
