EXAMPLE 6.2
In Example 5.4, we considered the random variables Y₁ (the proportional amount
of gasoline stocked at the beginning of a week) and Y2 (the proportional amount of
gasoline sold during the week). The joint density function of Y₁ and Y2 is given by
3y1, 0 ≤ y2 yı≤ 1,
f(y1, y2) =
0,
elsewhere.
Find the probability density function for U = Y₁ - Y₂, the proportional amount of
gasoline remaining at the end of the week. Use the density function of U to find E(U).

a
If U has a x² distribution with v df, find E(U) and V (U).
b Using the results of Theorem 7.3, find E(S2) and V (S2) when Y₁, Y2,..., Y, is a random
sample from a normal distribution with mean μ and variance o².
