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?
