Suppose that 11% of all steel shafts produced by a certain process are nonconforming but can be reworked (rather than having to be scrapped). Consider a random sample of 200 shafts, and let X denote the number among these that are nonconforming and can be reworked. (Round your answers to four decimal places.) USE SALT (a) What is the (approximate) probability that X is at most 30? 0.9726 (b) What is the (approximate) probability that X is less than 30? 0.9647 X (c) What is the (approximate) probability that X is between 15 and 25 (inclusive)? 0.6943 X You may need to use the appropriate table in the Appendix of Tables to answer this question.
