Answer 2

Using the mean formula, it is found that the average aerobics time per week for Stacy relative to her goal number of hours is of -0.172 hours.

------------------

• The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In this problem:

• The data-set has 5 observations, which are: {2.8, -2, 1.34, 0, -3}.

Thus, the mean is:

$M = \frac{2.8 - 2 + 1.34 + 0 - 3}{5} = -0.172$.

The average aerobics time per week for Stacy relative to her goal number of hours is of -0.172 hours.
