A researcher tested two new exercise routines, PowerHour, and MightyFifty on reducing heart rate. For Power Hour, each participant performs a routine consisting of 50 each of jumping jacks, push-ups, and sit ups in two 30-minute sessions every week for 6 weeks. With the MightyFifty, the participants perform the same routine but only for a total of 50 minutes each week. At the end of the six week period, he measured the heart rate of the participants. At the beginning, the mean of participants heart rate was 71.5. the end of the study, the mean heart rate of 6 participants in the PowerHour program was 69.5 with variance of 2.1, while that of 5 participants in t Mighty-Fifty program was 68.9 with standard deviation of 1.5.

Question
A researcher tested two new exercise routines, PowerHour, and MightyFifty on reducing heart rate. For Power Hour, each participant performs a routine consisting of 50 each of jumping jacks, push-ups, and sit ups in two 30-minute sessions every week for 6 weeks. With the MightyFIfty, the participants perform the same routine but only for a total of 50 minutes each week. At the end of the six week period, he measured the heart rate of the participants. At the beginning, the mean of participants' heart rate was 71.5.A the end of the study, the mean heart rate of 6 participants in the PowerHour program was 69.5 with variance of 2.1, while that of 5 participants in th Mighty-Fifty program was 68.9 with standard deviation of 1.5. The researcher concluded that the MightyFifty Program is significantly better in lowering the heart rate than the PowerHour Program. Is his claim true?
