To inspect manufacturing processes, companies typically examine samples of parts for deficiencies. One company that manufactures ballpoint pens selected samples of 1000 pens on each of 9 days. The company recorded, for each sample of 1000, the number of defective pens in the sample. Here are their data: 19, 16, 28, 35, 35, 30, 16,...
