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.) m use SALT (a) Calculate P(10.99 s is 11.01) when n = 16. P(10.99 s E g 11.01) = :l x (b) How likely is it that the sample mean diameter exceeds 11.01 when n = 25? P072 mm = :l
