Question 527822
 In a standard normal distribution, what z value corresponds to 17% of the data between the mean and the z value? 
----
Draw the picture and you will see there is a left-tail
of 50-17 = 33%.
invNorm(0.33) = -0.4399
By symmetry there is a point to the right of the mean where z = +0.4399
