1. The problem statement, all variables and given/known data

Problem 1 – Normal Random Variables

B) Y ~ N(300, 100). Pr (300 < Y < 320) = 0.4772

D) H ~ N(4000, 25). R = f(H) = 0.5H – 60. E(R) = 1940; Var(R) = 156.25





I have a problem solving these problems above...I missed the class when we covered this subject and now I am lost upon solving them.. I hope somebody can help, thanks a lot
