I need the CV for the systolic and diastolic measurements and then compare the variation

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 118 127 159 97 154 122 118 135 126 120 Diastolic 81 75 72 50 92 89 58 62 72 81 The coefficient of variation for the systolic measurements is % (Type an integer or decimal rounded to one decimal place as needed.)
