A sample of blood pressure measurements is taken for a group of adults, and those values (mm Hg) are listed below. The values are matched so that 10 subjects each have a systolic and diastolic measurement. Find the coefficient of variation for each of the two samples; then compare the variation. Systolic 116 130 157 96 158 120 118 137 126 119 Diastolic 81 77 75 53 88 86 58 65 70 84 The coefficient of variation for the systolic measurements is 14.9%. Type an integer or decimal rounded to one decimal place as needed.) The coefficient of variation for the diastolic measurements is %. Type an integer or decimal rounded to one decimal place as needed.)
