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.

The coefficient of variation for the systolic measurements is

nothing​%.

The coefficient of variation for the diastolic measurements is

nothing​%.

Compare the variation.

The coefficients of variation for each data set are = within 5 percentage points of each other more than 5 percentage points apart, ​Therefore, the systolic measurements vary

▼about the same as = significantly more than, significantly, less than the diastolic measurements.

Solutions

Expert Solution

coefficient of variation for the systolic measurements is =14.5 % (please try 14.52 % if required to 2 decimals)

coefficient of variation for the diastolic measurements is =17.5 %(please try 17.52 % if required to 2 decimals)

The coefficients of variation for each data set are within 5 percentage points of each other

Therefore, the systolic measurements vary about the same as diastolic measurements.
