Question 904979: Given that the ages of students doing bs is normally distributed with mean 25 years and variance 5 years, convert the following statements in X to those in Z. For each, sketch on the normal curve clearly showing the area required.
I. P(X<35)
II.P(X>30)
The first question was missing some infor please help.

Stick with what You know: sigma+=+sqrt%285%29
z+=+blue%28x+-+mu%29%2Fblue%28sigma%29
I. P(X<35) = P(z < %2835-25%29%2Fsqrt%285%29= P(z< 4.472) Z SO FAR TO RIGHT, GREEN LINE DOES NOT SHOW
II.P(X>30)= P(z > %2830-25%29%2Fsqrt%285%29 = P(z > 2.236)
