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, 1
4.21, 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.
What you would do is divide all of the minutes by the amount of pages to find how long for each rate for one page. (ex. 18/12, Michael reads 1 page in 1.5 minutes. 12/8, Michael reads 1 page in 1.5 minutes. 30/20, Michael reads one page in 1.5 minutes) Therefore, yes it is proportional, and the equation is y=1.5x (there is no y intercept)
