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

129

158

94

158

124

114

137

127

122

Diastolic

78

75

73

53

90

88

57

64

70

84

1) The coefficient of variation for the systolic measurements is __ % ?
2) The coefficient of variation for the diastolic measurements is __ %?
3) The coefficients of variation for each data set are [within 5 percentage points of each other OR more than 5% apart]. Therefore, the systolic measurements vary [signicantly more than, signifcantly less than, OR about the same]
