10.47 [EX10-047] A study was designed to estimate the difference in diastolic blood pressure readings between men and women. MINITAB was used to construct a 99% confidence interval for the difference between the means based on the following sample data.

Males 76 76 74 70 80 68 90 70 90 72 76 80 68 72 96 80 Females 76 70 82 90 68 60 62 68 80 74 60 62 72 Two-sample T for Males vs Females N Mean StDev SE Mean Males 16 77.37 8.35 2.1 Females 13 71.08 9.22 2.6 99% C.I. for mu males mu females: ( 2.9, 15.5)

Verify the results (the two sample means and standard deviations, and the confidence interval bounds) by calculating the values yourself. Assume normality of blood pressure readings.
