Find P(88 < X < 118) when X has a normal distribution with a mean of 100 and a standard deviation of 15.
Madhur L.
Assume that X is normally distributed with a mean of 5.5 and a standard deviation of 1.5. Determine the value of x that solves each of the following: a) P(X > x) = 0.5 b) P(X > x) = 0.95 c) P(x < X < 7) = 0.25 d) P(-x < X - 5 < x) = 0.95 e) P(-x < X - 5 < x) = 0.99
