A manufacturer of television wall mounts would like to make a chart to monitor the percentage of defective mounting brackets due to problems with drilled holes. These holes may be defective because they are off- center, out of round, or not drilled. Five samples, each of size 100, have been taken from the production process and the discrepancies are as follows: Percent defective 2.0 Sample 1 2 3 7.0 4 5.0 3.0 4.0 5 Using this information and a 3 standard deviation chart, the upper control limit is: Multiple Choice O 0.0025 O 0.0420 O O 0.0602 U O 0.1022
