Pulse Rates of Identical Twins A researcher wanted to compare the pulse rates of identical twins to see whether there was any
difference. Nine sets of twins were randomly selected. The rates are given in the table as number of beats per minute. Find the
98% confidence interval for the difference of the average pulse rates of twins. Assume the variables are normally distributed. Let
H, be the average of twin A and un = 4 - HR. Round the answer to at least one decimal place.
