Answer 2

D. No, Jacob is not correct. The median amount he makes is $84.00 in a day.

Explanation:

In this case, the mean is not the best measure of this data.

We can see that there is one value lower than the rest, $58. This brings the mean down.

With the value of $58, the mean is $80.70. If we were to take this value out, the mean would be $85.20, which is higher.

Since the mean is brought down by this value, we should use the median. The median of this data set is $84.
