Exercise 1: CPU Usage — Mean vs. Median — Possible Solution
====================================================================

GIVEN
------------------------------
45, 48, 50, 47, 46, 95

STEP 1: THE MEAN
------------------------------
Sum = 45 + 48 + 50 + 47 + 46 + 95 = 331
Mean = 331 / 6 ~= 55.17%

STEP 2: THE MEDIAN
------------------------------
Sorted: 45, 46, 47, 48, 50, 95
n = 6 (even), so the median is the average of the 3rd and 4th values:

  Median = (47 + 48) / 2 = 47.5%

STEP 3: WHICH BETTER REPRESENTS A "TYPICAL" READING
------------------------------
Five of the six readings sit between 45% and 50% - clearly the
"typical" range for this system. The mean (55.17%) is pulled well
above that entire typical range by the single 95% outlier, making it
look like CPU usage runs noticeably higher than it actually does most
of the time. The median (47.5%) sits comfortably inside the actual
typical range and barely reacts to the outlier at all.

Per this chapter's own outlier-resistance finding, the MEDIAN is the
better representative of a typical reading here - the mean is
distorted by the single unusual 95% spike in exactly the way this
chapter's own dashboard-averaging example demonstrated.

WHY THIS WORKS AS AN ANSWER
------------------------------
Both statistics are computed directly using this chapter's own
formulas, and the comparison is grounded in this chapter's own
finding about the median's resistance to outliers, explicitly pointing
to how the mean gets pulled outside the range where most of the real
data actually sits.
