Question

A study was conducted to determine whether or not there was equalvariability in male and female systolic blood pressure readings.Random samples of 16 men and 13 women were used to test theexperimenter's claim that the variances were unequal. MINITAB wasused to calculate the standard deviations, F, and the p value.Assume normality

Men    120 120 118 112 120 114 130 114 130 114 124125 130 100 120 108 112 122

Women 122 102 118 126 108 130 104 116 102 122 120 118 130

Standard deviation of Men- 7.8864
Standard deviation of Women- 9.9176
F-Test (normal distribution)
Test Statistic: 1.581
P Value- 0.398

Verify these results by calculating the values yourself
