Aresearcher was interested in comparing the resting pulse rate of people who exercise regularly and people who do not exercise regularly. independent simple random samples of 16 people ages 30-40 who do not exercise regularly and 12 people ages 30-40 who do exercise regularly were selected and the resting pulse rate of each person was measured. the summary statistics are as follows. do not exercise x1=72.3 s1=10.3 n1=16 do exercise x2=69.0 s2=8.9 n2=12 at the 2.5% significance level, do the data provide sufficient evidence to conclude that the mean resting pulse rate of people who do not exercise regularly is greater than the mean resting pulse rate of people who exercise regularly? use the critical-value approach.
