You know that P(X>4) = 84.13% and that P(X>7) = 30.85% Also X~N…. You know that P(X>4) = 84.13% and that P(X>7) = 30.85% Also X~N. Find µ and ?2! (Harder – write out what you have in the appropriate equations and see what is missing – if you do it right you will have two equations and two unknowns which you can solve.)
