jenny is 5'10" tall. the heights of the girls in the school are approximately normally distributed with a mean of 5'5" and a standard deviation of 2.6". What is the percentile of jenny's height?
Z = (score-mean)/SD
Insert the values to find Z. Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion related to that Z score.
