Answer:
Option C.
Step-by-step explanation:
For a given set of N elements:
{x₁, x₂, ..., xₙ}
The mean is given by:
And the variance is given by:
Then for our set:
{70, 80 ,75, 75, 80}
We have 5 elements, then N = 5
The first thing we need to find is the mean.
Then the variance will be:
The correct option is C, 14.
Visibly, the functions g(x) and f(x) have restricted domains, while p(x) seems to go on infinitely. The answer is "Only p(x)."
