B. Based on your p-chart and the data from the last 3 weeks, what can you conclude about the absenteeism of nurses' aides?

Use the control limits from part (a) to determine if the process is out of control in the last 3 weeks. If any of the sample points fall outside of the control limits, then the process it out of statistical 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. To get the facts, absenteeism data were gathered for the last three weeks, which is considered a representative period for future conditions. After taking random samples of 60 personnel files each day, the following data were produced: Day Aides Absent 1 2 Aides Absent 8 1 Day 6 7 8 9 10 5 5 3 8 8 Day 11 12 13 14 15 Aides Absent 7 7 10 3 2 4 5 8 6 Because your assessment of absenteeism is likely to come under careful scrutiny, you would like a type I error of only 1 percent. You want to be sure to identify any instances of unusual absences. If some are present, you will have to explore them on behalf of the registered nurses. a. Design a p-chart. The upper control limit is and the lower controllimit is (Enter your responses rounded to three decimal places. If your answer for the lower control limit is negative, enter this value as 0.)
