Using the mean concept, it is found that the mean difference between the call times and the  company's average call time is given by:

  • C. 0.4

<h3>What is the mean?</h3>
  • The <em>mean </em>of a data-set is given by the <u>sum of all observations in the data-set divided by the number of observations</u>.

In this problem:

  • The four observations are the differences between the time of each phone call and the average time.
  • They are: {-2.32, -1.55, 4.79, 0.68}

Hence, the mean difference is:

M = \frac{-2.32 - 1.55 + 4.79 + 0.68}{4} = 0.4

Hence, option C is correct.
