Question
![K
In this section, we are mainly interested in findings the probability distribution of the
sample mean X and sample variance S², that is distribution of the statistics of samples.
Example 2.2.1
Let X₁ and X₂ be a random sample of size 2 from a distribution with the probability
density function
f(x) =
=
(6x(1-x), 0<x< 1
0,
otherwise
What are the mean and variance of the sample sum T = X₁ + X₂?
