g I produce candies that have weight with mean 4 and standard deviation 0.33 (assuming normal distribution). I take a random sample of 9 candies, weigh them, and compute the average. If the average exceeds 6 or is less than 3.4 I stop production because I believe the candies are overweight or underweight. .869 Find the probability the average weight of 9 candies is acceptable, i. e. between 3.5 and 4.5. Instead of finding the average of a sample to accept the process, the quality control engineer checks the weight of every unit in the sample. What is the probability of finding two unacceptable units in the sample.
