Please help me with this.

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. a. Assuming 10 observations are adequate for this purpose, determine the three-sigma control limits for dimples per camper top. The UCLC equals and the CLC equals (Enter your responses rounded to two decimal places. If your answer for LCLC is negative, enter this value as 0 .) b. Suppose that the next camper top has 18 dimples. What can you say about the process now? A. The number of defects is greater than the upper control limit, so the process is not in control. B. The number of defects is greater than the upper control limit, so it is assumed that the proces's is in controt. C. The number of defects is less than the upper control limit, so the process is not in control. D. Since the number of defects is close to the upper control limit, the results are inconclusive. E. The number of defects is less than the upper control limit, so it is assumed that the process is in control
