question 125

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 is known to produce 11 percent defectives on average, using three-sigma control limits, do any of the sample proportions indicate an out-of-control process proportion of defectives?
