The Big Black Bird Company produces fiberglass camper tops. The process for producing the tops must be controlled so as to keep the number of dimples low. When the process was in control, the following defects were found in 10 randomly selected camper tops over an extended period of time: Top Dimples1 72 93 144 115 36 127 88 49 710 6a. Assuming 10 observations are adequate for this purpose, determine the three-sigma control limits for dimples per camper top.b. Suppose that the next camper top has 15 dimples.

Researchers conducted a study to determine whether magnets are effective in treating back pain. Pain was measured using the visual analog scale, and the results shown below are among the results obtained in the study. Higher scores correspond to greater pain levels.
