Why is it necessary to include units when reportingscientific measurements?
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 0-4, 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 from the run chart?
