Question

suppose that a college men's heights are approximately normally distributed with a mean of 70 inches and a population standard deviation of 3 inches. What height is at the lowest 15% level?

Answer 1

Using Z = X - mean / standard deviation

P(X<Z) =0.15

We get Z=-1.04

Find X=mean + standard deviation(-1.04)

We get X=66.88
