Answer

Explanation:

Step1: Recall total number formula

The total number of individuals is the sum of frequencies.

Step2: Calculate sum of frequencies

$8 + 24+12 + 3+4=51$

Step3: Analyze original values

In a frequency - table with class intervals, we cannot identify the exact original values as the data is grouped.

Answer:

51; It is not possible to identify the exact values of all of the original service times.
