It is suspected that the mean may have changed over a long period of use. To test for this possibility, a sample of 250 components is drawn and the mean is computed at 0.165. Using the assumption that μ is true; determine whether there is any evidence at the 5% level that the mean of the components has changed. c. Use the binomial distribution to find the probability that two blanks selected at random from a sample of five will be oversize, use the probability of a blank being oversize in either dimension found in part b. d. Use the Poisson distribution to find the probability that three blanks selected at random from a box of 25 will be oversize, using the probability of a blank being oversized in either dimension found in part
