. Prepare a run diagram for this emergency call data. Use five-minute intervals (i.e., count the calls
received in each five-minute interval. Use intervals of 0 to 4, 5 to 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 from the run chart?
