Question

Your company takes orders over the phone. The company’s average call time is 4.6 minutes. The graph below shows 4 calls and the difference between the call time and the company’s average call time. For these 4 calls, what is the mean difference between the call times and the company’s average call time, rounded to the nearest 0.1 minute?
(Note: A negative difference indicates the call is shorter than the average.)

Answer 1

The mean difference between the call times and the company’s average call time is 0.4.

How to calculate the mean?

It should be noted that mean also means average.

Based on the information given, the mean of the numbers will be:

= -2.32 + -1.55 + 4.79 + 0.68 / 4

= 1.6/4

= 0.4

Therefore, the mean difference between the call times and the company’s average call time is 0.4.
