Systolic blood pressure was measured for the random sample of 260 smokers and random sample of 53 non-smokers (i.e. currently do not smoke). The sample mean and variance for smokers are 115 as well as 13.4 mm Hg, respectively. The sample mean and variance for non-smokers are 114 and 10.1 mm Hg, respectively. Perform appropriate t-test to compare the mean systolic blood pressure between two populations using ?=0.05. You may suppose that the variances of two populations are equal. What do you conclude?
