[See Solution] A medical researcher suspects that the pulse rate of smokers is higher than the pulse rate of non-smokers. Use the sample statistics below
Question: A medical researcher suspects that the pulse rate of smokers is higher than the pulse rate of non-smokers. Use the sample statistics below to test the researcher's suspicion. Use a = 0.05.
Smokers n1 = 100 x1 = 86 s1 = 4.8
Nonsmokers n2 = 100
x2 = 83 s2 = 5.3
