The inside diameter of a randomly selected piston ring is a random variable with mean value 14 cm and standard deviation 0.05 cm. Suppose the distribution of the diameter is normal. (Round your answers to four decimal places.) in USE SALT (a) Calculate P(13.99 < X < 14.01) when n = 16. P(13.99 X 14.01) = (b) How likely is it that the sample mean diameter exceeds 14.01 when n = 25? P(X > 14.01) =
