A production manager at a contour manufacturing plant has inspected the number of defective plastic molds in five random samples of 15 observations each. Following are the number of defective molds found in each sample:

Number of \begin{tabular}{ccc} Sample & NumberofDefects & ObservationsinSample \\ 1 & 2 & 15 \\ 2 & 3 & 15 \\ 3 & 0 & 15 \\ 4 & 3 & 15 \\ 5 & 1 & 15 \\ \hline Total & 9 & 75 \end{tabular} 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.)
