Find difference between pulse rates smokers-nonsmokers

Reference no: EM13137658

In a statistics class of 15 students there are 6 smokers. The smokers have pulse rates of: 68, 80, 98, 100, 88, 92. The nonsmokers have pulse rates: 84, 60, 63, 86, 78, 68, 91, 63, 72. Do a relevant test to determine if there is any dierence between the pulse rates of smokers and nonsmokers. Compute the p-value of the test. Can you draw any conclusions?
