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.

A sample of blood pressure measurements is taken from a data set
and those values (mm Hg) are listed below. The values are matched
so that subjects each have systolic and diastolic measurements.
Find the mean and median for each of the two samples and then
compare the two sets of results. Are the measures of center the
best statistics to use with these data? What else might be
better?

Recorded in the table below are the blood pressure measurements
(in millimeters) for a sample of 12 adults. Does there appear to be
a linear relationship between the diastolic and systolic blood
pressures? At the 5% significance level, test the claim that
systolic blood pressure and diastolic blood pressure have a linear
relationship.
