A medical team was asked to study the difference in systolic blood pressure (BP) between men (µ1) and women (µ2) with heart trouble. The BP measurements are normally distributed. The variance of the men’s group is equal to that of the women’s group. For a random sample of 4 men, thesample average is 175 and the sample standard deviation is 16. For a random sample of 5 women, the sample average is 145 and the sample standard deviation is 12. Assuming independent populations with equal variances, what is the value of the test statistic? 6.16 1.75 3.23 1.91
