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 alpha risk (probability of Type I error) for upper and lower control limits of .115 and .085 respectively? .13 and .07? .145 and .055?
