A boy threw a ball 25 times. Kinetic energy of the ball is as follows: 25.66, 30.71, 18.32, 16.77, 24.05, 19.49, 14.22, 20.03, 14.21, 28.43, 28.03, 22.07, 29.48, 14.91, 17.12, 15.12, 27.97, 23.02, 23.37, 27.55, 23.48, 19.90, 15.78, 28.88, 29.71 J. Calculate a point estimate of the proportion of all ball throws whose energy deviation from the mean is larger than the standard deviation. Round your answer to two decimal places (e. g. 98.76).
