A particular quality characteristic of a product has a single lower specification of 1.0 units. It is desired to use variables sampling to sentence production batches. Using the k method (procedure 1) Part 1 Design a sampling plan for the situation where s is unknown and p1=0.01, p2=0.20, a =0.05, b =0.10   Question 1: n = ? Question 2: k=? Question 3: For this variables sampling plan, suppose that a sample of the appropriate size was taken and resulted in an average = 1.82, with s=0.31. Should this batch be accepted or rejected?
