- A vendor converts the weights on the packages she sends from pounds to kilograms (1 kg ≈ 2.20 lb). The mean weight of the package was 21 lb with standard deviation of 0.31 lb. After repackaging (converting units), the mean becomes kg (round your answer to 2 decimal places), and the standard deviation becomes kg (round your answer to 2 decimal places).arrow_forwardThe frequency distribution was obtained using a class width of 0.5 for data on cigarette tax rates.

- 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?
