A factory collected data on the number of nonconforming parts and constructed a p-chart. 15 samples of size 150 were collected. They determined that the average fraction of non-conforming parts was pbar=0.037. During production, a sample of 150 parts was taken, of which 11 were non-conforming. At the time this sample was taken: a. the lower control limit was -0.01 b. the sample was outside the control limits c. the sample was within the control limits d. the upper control limit was 0.073 3. What is the upper control limit for a…arrow_forward
