I need help with the final step... X~N(25,81) Solve for: P(24<X<43) P(24<X<43) = P(24-25)/√81<(X-25)/9<(43-25)/9 P=(-1/9<Z<2) =ϕ(0,11) - ϕ2 = ??? I would be grateful if anyone could help me! Thanks!

Hey emme1. Hint: P(-1/9 < Z < 2) = P(Z < 2) - P(Z < -1/9) where you can find these probabilities with either a computer or with statistical tables. Have you done this before?
