The finished inside diameter of a piston ring is normally distributed with a mean of 11centimeters and a standard deviation of 0.02 centimeter. Complete parts (a) through (c) below. (a) What proportion of rings will have inside diameters exceeding 11.054 centimeters? (Round to four decimal places as needed.) (b) What is the probability that a piston ring will have an inside diameter between 10.98 and 11.02 centimeters? (Round to four decimal places as needed.) (c) Below what value of inside diameter will 20% of the piston rings fall?
