Product filling weights are normally distributed with a mean of 345 grams and a standard deviation of 12 grams. a. Compute the X chart upper control limit and lower control limit for this process if samples of size 10, 20 and 30 are used (to 2 decimals). Use Table 19.3. For samples of size 10 UCL LCL For a sample size of 20 UCL LCL For a sample size of 30 UCL LCL b. What happens to the limits of the X chart as the sample size is increased? Select c. What happens when a Type I error is made? Select d. What happens when a Type II error is made? Select e. What is the probability of a Type I error for samples of size 10, 20 and 30 (to 4 decimals)? f. What is the advantage of increasing the sample size for control chart purposes? What error probability is reduced as the sample size is increased? Select
