A machine precision-cuts tubing such that ? = 38.00 in. and ? = 0.05 in. If the lengths are normally distributed, find the probability that a piece of tubing selected at random measures as follows. (Round your answers to four decimal places.) (a) greater than 38.05 in. (b) less than 38.045 in. (c) between 37.95 and 38.05 in. You may need to use the table of areas under the standard normal curve from the appendix.
