Homework Answers

Answer #1

The question is incomplete because I need time and frequency table to calculate. Anyway i will give an example table and answer, which will help you to calculate the table which you have

how many individuals are included in the summary?

The number of individuals in the summary is then the sum of all frequencies

=7+22+14+2+5 = 50

is it possible to identify the exact values of all of tje original service times ?

It is not possible to determine the exact values of all the original service times, because we only know the number of values that fall within a certain time interval, but we do not know which time within the interval
