Given the Following Process Control Data for a Quality Attribute $$\begin{array} { l r } \text { Sample } & \text { Defectives } \\\hline \# 1 & 36 \\\# 2 & 32 \\\# 3 & 52\end{array}$$

Short Answer

Given the following process control data for a quality attribute (three samples of size 400 each): $$\begin{array} { l r } \text { Sample } & \text { Defectives } \\\hline \# 1 & 36 \\\# 2 & 32 \\\# 3 & 52\end{array}$$ If the process proportion of defectives is unknown, what is the estimate of this proportion?
