Final answer:
To determine the flow rate of callers from 8:00 to 8:25 am, refer to Table 2.5 and find the number of callers during that time period.
Step-by-step explanation:
To determine the flow rate of callers from 8:00 to 8:25 am, we need to refer to the data provided in Table 2.5. Identify the column that represents the time interval from 8:00 to 8:25 am. Then, find the corresponding entry in that column, which indicates the number of callers during that time period. This number represents the flow rate of callers from 8:00 to 8:25 am.
