Question 2

A company that makes tennis balls controls its production process by periodically taking a sample of 100 balls from the assembly line. Each ball is checked for defective features. P-chart control limits are developed using 3 standard deviations from the mean as the limit. During the last 15 samples taken, the percentage of defective items per sample was recorded as follows:

$ \begin{array}{llllllll}.02 & .01 & .03 & .01 & .01 & .02 & .00 & .02 \ .00 & .01 & .03 & .03 & .02 & .02 & .01 & \end{array} $

Compute the mean percent defective.
 a. Compute the UCL and the LCL.

Accepted Answer

? a. The mean proportion defective (center line) calculated was consistent with the long run mean percentage defective.
$$\begin{array}{l}
\mathrm{CL}=.02+.01+.03+.01+.01+.02+.00+.02+ \
\frac{.00+.01+.03+.03+.02+.02+.01}{15} \
=.016 \
\end{array}$$
b.
$$\begin{aligned}
\mathrm{UCL} & =.016+3 \sqrt{\frac{.016(.984)}{100}} \
& =.016+.0376 \
& =.0536 \
\mathrm{LCL} & =.016-3 \sqrt{\frac{.016(.984)}{100}} \
& =.016-.0376 \
& =-.0216 \text { which is negative }
\end{aligned}$$

Therefore, the LCL $ =0 $
