Question

Quizplus · Accepted Answer

The earliest due date criterion means that jobs are scheduled in order of their due date, with the job with the earliest due date being scheduled first.
Using the data in the table, we can determine the lateness for each job by subtracting its due date from its completion time. The lateness values for each job are:
Job 1: 2
Job 2: 7
Job 3: 5
Job 4: 0
Job 5: 5
Job 6: 8
Job 7: 3
To calculate the average lateness, we add up all of the lateness values and divide by the total number of jobs:
(2 + 7 + 5 + 0 + 5 + 8 + 3) / 7 = 30 / 7 = 4.29
Therefore, the answer is not given in the options. However, if we round up the answer to the nearest whole number, we get 4. Therefore, the best choice would be option C, which is closest to the rounded-up value of 4.
