Using the Chi-Square Test procedure, you found that the rate at which patients are discharged from the hospital is not constant over the course of an average week. This is largely due to greater numbers of discharges on Friday and vastly fewer numbers of discharges on Sunday. When you restricted the range of the test to weekdays, the discharge rates appeared to be more uniform. You may be able to correct staff shortages by adopting separate weekday and weekend staff schedules.
