2. Let the random variable X have the density function,
f(x;0) = (1/0)e-x/0, 0 < x < ∞,
Consider the simple hypothesis Ho: 0 = 0' = 2 and the alternative hypothesis H₁: 0 = 0″ = 4.
Let X1, X2 be a random sample of size 2 from this distribution. Show that the best hypothesis
test of Ho vs H₁ can be carried out with the statistic X₁ + X₂. Elaborate in detail.
