You are working in a small, student-run company that sends out merchandise with university branding to alumni around the world.
topjm [15]

Answer:

The answer is "0.142466".

Step-by-step explanation:

Using the p formula for the proportion of nonconforming units through the subgrouping which can vary in sizes:

p =\frac{np}{n}\\\\

\bar{p}=\frac{\Sigma np}{\Sigma n}\\\\

Defects = \frac{5}{100} \times 50 \\\\

p = \frac{5}{100} \times \frac{50}{50}=0.05\\\\

It calculates the controls limits through the p-chart that is:

UCL_{p},LCL_{p}=\bar{p} \pm \sqrt{\frac{\bar{p}(1-\bar{p})}{\bar{n}}}\\\\

So, the upper control limits:

= 0.05 + 3 \times \sqrt{(\frac{0.05\times(1-0.05)}{50})} \\\\= 0.142466
