Short Answer

SCENARIO 18-6
The maker of a packaged candy wants to evaluate the quality of her production process. On each of
16 consecutive days, she samples 600 bags of candy and determines the number in each day's sample
that she considers to be of poor quality. The data that she developed follow. $$\begin{array} { r c c } \underline {\text { Day }} & \begin{array} { c } \text { Number } \\\underline {\text { Poor }}\end{array} & \begin{array} { c } \text { Proportion } \\\underline {\text { Poor }}\end{array} \\1 & 33 & 0.0550000 \\2 & 29 & 0.0483333 \\3 & 31 & 0.0516667 \\4 & 32 & 0.0533333 \\5 & 43 & 0.0716667 \\6 & 45 & 0.0750000 \\7 & 46 & 0.0766667 \\8 & 48 & 0.0800000 \\9 & 48 & 0.0800000 \\10 & 46 & 0.0766667 \\11 & 28 & 0.0466667 \\12 & 32 & 0.0533333 \\13 & 28 & 0.0466667 \\14 & 32 & 0.0533333 \\15 & 31 & 0.0516667 \\16 & 24 & 0.0400000\end{array}$$
-Referring to Scenario 18-6, a p control chart is to be constructed for these data. The estimate of
