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           Dimples
1                     7
2                     9
3                   14
4                   11
5                     3
6                   12
7                     8
8                     4
9                     7
10                   6

a. 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. What can you say about the process now?
