![Heart rates are determined before and 30 minutes after a Kettleball workout. It can be assumed that heart
rates (bpm) are normally distributed. Use the data provided below to test to determine if average heart rates
prior to the workout are significan tly lower than 30 minutes after a Kettleball workout at the 0.02 level of
significance. Let µi = mean before workout.
