A doctor wishes to see whether the pulse rates of smokers are higher than the pulse rates of non-smokers. Sample of 102 smokers and 100 non smokers are selected. The results are given as the average of smokers and non smokers are 89 and 86 respectively and the population variances of smokers and non smokers are as 25 and 36 respectively. Can the doctor conclude, at α = 0.01, that smokers have higher pulse rates than nonsmokers ?
