Hello! No need to show all work but please help me but answering all the parts, it is multiple choice so just point out the correct answer! Please help for all parts! thanks!

Consider a process with an upper spec limit of 160 grams, a lower spec limit of 150 grams, and a mean of 157 grams. If the standard deviation is 1 gram, which one is correct about the process capability? A. The process capability index is 1 and the process is capable B. The process capability index is 1 and the process is not capable. C. The process capability index is 2.33 and the process is capable. D. The process capability index is 2.33 and the process is not capable. E. It is not clear whether the process is capable or not. Given the following data, use exponential smoothing (a=0.2) to develop a demand forecast for period 3. Assume the forecast for the initial period is 4. What is the forecast for period 3? Period Demand Forecast 1 2 3 6 10 A. 4.00 B. 4.40 C. 5.52 D. 6.62 E.10.20 Consider the all-units quantity discount schedule below.
