A study shows that running increases the percent resting metabolic rate (RMR) in older women. The average RMR of 25 elderly women runners was 34.7% higher than the average RMR of 25 sedentary elderly women, and the standard deviations were reported to be 10.5% and 10.3%, 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.
