Answer #1

Given mean = 156 and standard deviation =21

All 64 male athletes follow bell shaped distribution with above mean and standard deviation

According to empirical rule of probability, 99% of data lies between (mean -3*SD, mean +3*SD)

99% of data lies between (mean-3*SD, mean+3*SD) = (156-3*21, 156+3*21) = (93, 219)
