When you have your blood pressure taken, the larger number is the systolic blood pressure. Using data from NHANES, we looked at whether men and women have different systolic blood pressure levels.
a. Report the two sample means, and state which group had the higher sample mean systolic blood pressure. Refer to the Minitab output in figure (A).
b. Refer to the Minitab output given in figure (A) to test the hypothesis that the mean systolic blood pressures for men and women are not equal, using a significance level of 0.05. Although the distribution blood pressures in the population are right-skewed, the sample size is large enough for us to use t-tests. Choose from figures (B), (C), and (D) for your t and p-values, and explain.
