Find the means
The mean for systolic is mm Hg and the mean for diastolic is mm Hg.
(Type integers or decimals rounded to one decimal place as needed.)
Find the medians,
The median for systolic is mm Hg and the median for diastolic ismm Hg.
(Type integers or decimals rounded to one decimal place as needed.)
Compare the results. Choose the correct answer below.
O A. The median is lower for the diastolic pressure, but the mean is lower for the systolic pressure
O B. The mean and the median for the diastolic pressure are both lower than the mean and the median for the systolic pressure
O C. The mean and median appear to be roughly the same for both types of blood pressure
OD. The mean and the median for the svstolic, nressure are hoth lower than the mean and the median for the diastolic nressure

O A. The median is lower for the diastolic pressure, but the mean is lower for the systolic pressure.
.....
O B. The mean and the median for the diastolic pressure are both lower than the mean and the median for the systolic pressure.
O C. The mean and median appear to be roughly the same for both types of blood pressure.
O D. The mean and the median for the systolic pressure are both lower than the mean and the median for the diastolic pressure
O E. The mean is lower for the diastolic pressure, but the median is lower for the systolic pressure.
Are the measures of center the best statistics to use with these data?
O A. Since the sample sizes are equal, measures of center are a valid way to compare the data sets.
O B. Since the systolic and diastolic blood pressures measure different characteristics, a comparison of the measures of center doesn't make sense.
O C. Since the sample sizes are large, measures of center would not be a valid way to compare the data sets.
O D. Since the systolic and diastolic blood pressures measure different characteristics, only measures of center should be used to compare the data sets.
