The inside diameter of a randomly selected piston ring is a random variable with mean value 11 cm and standard deviation 0.02 cm. Suppose the distribution of the diameter is normal. (Round your answers to four decimal places.) USE SALT (a) Calculate P(10.99 ≤ X ≤ 11.01) when n = 16. P(10.99 X 11.01) = (b) How likely is it that the sample mean diameter exceeds 11.01 when n = 25? P(X 11.01) = You may need to use the appropriate table in the Appendix of Tables to answer this question.
