find the coefficient of variation for each of the two samples

21. Blood Pressure A sample of blood pressure measurements is taken from Data Set 1 "Body Data" in Appendix B, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Systolic: 118 128 158 96 156 122 116 136 126 120 Diastolic: 80 76 74 52 90 88 58 64 72 82In Exercises 21-24, find the coefficient of variation for each of the two samples; then com- pare the variation.
