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 defects shown to the right were found in 10 randomly selected camper tops over an extended period of time.                                                        Top Dimples 1 7 2 8 3 12 4 9 5 4 6 14 7 7 8 3 9 6 10 8 a. Assuming 10 observations are adequate for this​ purpose, determine the three​-sigma control limits for dimples per camper top.   The UCLc equals nothing and theLCLc equals nothing. ​(Enter your responses rounded to two decimal places. If your answer for LCLc is​ negative, enter this value as 0.​)
