Flaws Are Counted on a Standard Steel Plate (Sheet) The Upper Control Limit (UCL) for the Steel Plate Control

Flaws are counted on a standard steel plate (sheet) . Each sheet has the exact same dimensions. If 10 sheets are selected at random and the number of flaws per sheet is as follows, determine the lower and upper control limits. $\begin{array} { | c | c | } \hline \text { Sheet } & \text { Number of Flaws } \\\hline 1 & 3 \\\hline 2 & 1 \\\hline 3 & 3 \\\hline 4 & 0 \\\hline 5 & 2 \\\hline 6 & 2 \\\hline 7 & 0 \\\hline 8 & 1 \\\hline 9 & 1 \\\hline 10 & 2 \\\hline\end{array}$ The upper control limit (UCL) for the steel plate control chart is _____.

A) less than 3
B) more than or equal to 3 but less than 4
C) more than or equal to 4 but less than 5
D) more than or equal to 5 but less than 6
