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 117 128 158 94 158 120 114 138 124 1219 Diastolic 79 77 76 50 88 62 70 80 87 56 The coefficient of variation for the systolic measurements is %. (Type an integer or decimal rounded to one decimal place as needed.)
