Please help me solve, thank you in advance :)

I need to find the CL, UCL, and LCL.

A production manager at a Contour Manufacturing plant has inspected the number of defective plastic molds in five random samples of 10 observations each. Following are the number of defective molds found in each sample: Construct a 3-sigma control chart (z=3) with this information. (If the lower control limit is negative, round the LCL to zero and all other answers to 2 decimal places, e.g. 15.25.)
