Quizplus · Accepted Answer

In order to calculate average job tardiness, we need to find the total tardiness and divide it by the number of jobs.

Total tardiness = (-3) + 3 + 0 + (-1) + 5 + (-2) + 2 + (-4) 
= -1

Number of jobs = 8

Average job tardiness = (-1)/8 = -0.125 days = -1.5 hours

However, the question asks for the average job tardiness in days, so we need to convert the answer to days by dividing it by 24:

Average job tardiness = -0.125/24 = -0.0052 days

Rounding to one decimal place, we get:

Average job tardiness = -0.01 days ≈ 0 days

Therefore, the best choice is B) 1.5 days.
