Listed below are the systolic blood pressure measurements (in mm Hg) of a random sample of Americans who are 40 years old and over and a random sample of Americans who are under 40 years Use a 0.01 significance level to test to see if Americans who are under 40 years of age have a lower blood pressure than Americans who are 40 years old and over. 40 and older: 175 169 182 146 144 90 92 103 95 105 106 Under 40: 102 101 94 79 79 100 80 85 90 75 Construct the appropriate hypothesis test using the critical value method. Be sure to complete and number all steps! Construct the appropriate 95% confidence interval for data above. Do the results of the confidence interval confirm the results in the hypothesis test? Why or why not?
