Prepare a run diagram for this emergency call data. Use five minute intervals (count calls received in each five minute interval. Use intervals of 0-4, 5-9, etc). Note: two or more calls may occur in the same minute; there were three operators on duty this night. What can you conclude form the run chart? please be very detailed.
