HW assist with calculations

Use this information to answer questions 17-19:

Southwest Hospital nurses and supervisors believe that high absenteeism among nurse aides in the past month has been a problem and it affects quality of service to their patients. You have been assigned to investigate this problem, using one of the methods you learned in MBA studies. Selecting samples of 100 aides files and controlling their absence for every other day of the past month, you have the following data:

Day	1	2	3	4	5	6	7	8	9	10	11	12	13	14	15
Number of aides absent	5	8	11	15	4	8	9	1	4	6	14	19	3	5	8

1. In which of the following ranges you can find the Upper Control Limit of your control chart? Keep 4 decimals in all calculations
   1. 0.1300 to under 0.1400
   2. 0.1400 to under 0.1500
   3. 0.1500 to under 0.1600
   4. 0.1600 to under 0.1700

1. In which of the following ranges you can find the Lower Control Limit of your control chart?
   1. -0.0030 to under 0
   2. 0 to under 0.0030
   3. 0.0030 to under 0.0040
   4. 0.0040 to under 0.05

1. Investigation shows that:
   1. Absenteeism is not a problem, it is in state of statistical control
   2. Absenteeism is not a problem for now, but the trend indicates problems in the future
   3. Absenteeism is out of statistical control because you found one day out of the control limits
   4. Absenteeism is out of statistical control because you found two days out of the control limits
   5. Absenteeism is out of statistical control because you found three days out of the control limits
