The following data are from a product process that makes approximately 350 units each hour. The data were collected over a normal 12-hour shift one day. Historical data shows the proportion of defects to be 5.84%. Use 350 as an approximation for all the sample sizes. Complete parts a through c.

The center line is p= (Round to four decimal places as needed.) b. Create a p chart for these samples. Use 350 as an approximation for the sample size when computing the control limits. Use the actual sample sizes when computing the sample proportions. Choose the correct chart below. OA.

The process is out of control because nine points in a row are outside of 16 on the same side. OB. The process is out of control because there are six increasing or decreasing points in a row. OC. The process is out of control because one point is outside the 3o linos. OD. The process is out of control because there are fourteen points in a row that alternate up and down. O E. The process is in control
