Question

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 117 128 156 98 155 123 118 137 127 121
diastolic 79 77 75 53 91 89 58 66 70 81
the coefficient of variation for the systolic measurements is 13.7 %. (type an integer or decimal rounded to one decimal place as needed.)
the coefficient of variation for the diastolic measurements is 16.6 %. (type an integer or decimal rounded to one decimal place as needed.)
compare the variation.
the coefficient of variation for the systolic data set is
set. therefore, the systolic measurements vary

Explanation:

Step1: Compare the coefficients of variation

The coefficient of variation for systolic is 13.7% and for diastolic is 16.6%.

Step2: Determine the relationship

Since 13.7% < 16.6%, the systolic measurements vary less than the diastolic measurements.

Answer:

less than; less than
