Using it's concept, the mean of data usage is of: 3.275.
<h3>What is the mean?</h3>
The mean 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 8 observations are given by:
3.6 1.8 1.5 3.5 3.1 5.4 2.8 4.5
Hence the mean is given by:
M = (3.6 + 1.8 + 1.5 + 3.5 + 3.1 + 5.4 + 2.8 + 4.5)/8 = 3.275.

You may recognize the numbers as belonging to the (5, 12, 13) Pythagorean triple. The runners traveled 12 km west after traveling 5 km south. Their total distance was ...
5 km +12 km = 17 km
_____
By the Pythagorean theorem, ...
(straight-line distance)² = (distance south)² +(distance west)²
In km, this is
13² = 5² +(distance west)²
169 -25 = (distance west)²
√144 = 12 = distance west
