5. Two processes A and B, were used to produce stainless steel shafts in an industrial company. Process A and Process B produce 9% and 12% nonconforming stainless steel shafts, respectively. a. A random sample of 100 stainless steel shafts were taken from Process A. What is the probability that more than 95% of the stainless steel shafts are conforming? UTM b. A random sample of 90 stainless steel shafts from Process A and 80 stainless steel shafts from Process B were taken randomly. Find the probability that the difference between proportion of the nonconforming stainless steel shafts from Process A and Process B is at most 0.1. UTM UTM
