A) For the p-chart, find the upper and lower control limits. Enter your response rounded to three decimal places.

B) Based on your p-chart and the data from the last three weeks, what can we conclude about the absenteeism of nurses aides?

a) The proportion of absent aides from day 14 is above the UCL, so the process is not in control.

b) The proportion of absent aides from day 15 is below the LCL, so the process is not in control.

c) All sample proportions are within the control limits, so the process is in control.

d) The proportion of absent aides from day 13 is above the UCL, so the process is not in control.

As a hospital administrator of a large hospital, you are concerned with the absenteeism among nurses' aides. The issue has been raised by registered nurses, who feel they often have to perform work normally done by their aides.
