Question 393144: Suppose the Q-angles (measured standing) for a population of young adult women are normally distributed with a mean of 19� and standard deviation of 8�. Let us call this variable X.Using z score formula z= (X-mean)/s, find out the X-value that represents the 35th percentile of the distribution.

Hi



 z = -.3853 for the 35 percentile using excel function NORMSINV(0.35)

 -.3853*8 = X - 19

 19 - .3853*8 = X

      15.9176 = X
