a$\mathrm{.}6$ Assuming Janice Sanders is willing to use three$-$sigma control limits$,$ construct the upper and lower control limits$.$

The $UC{L}_p$ equals and the $LC{L}_p$ equals $($Enter your responses rounded to four decimal places. If your answer for $LC{L}_p$ is negative, enter this value as $0.)$

b$.$ Based on your control limits and the data in the table, what can you conclude about the waiting time of the patients?

A$.$ At least one of the sample proportions is below the lower control limit$,$ so the process is not in control.

B$.$ All of the sample proportions are within the control limits and there are no unusual patterns, so the process is in control.

C$.$ The p$-$chart shows a significant upward trend, so the process is not in control.

D$.$ At least one of the sample proportions is above the upper control limit$,$ so the process is not in control.

E$.$ The p$-$chart shows a significant change in the wait times, so the process is not in control.
