4. Consider a single observation of a random variable having an exponential distribution A. Recall that Ix(2) = t,x >0. We have a hypothesis test: H : A= 2 Hi: A=1. The rejection region is C = {X < K}. (a) Decide K so that the test has size a. (b) Compute the probability of type II error of this test.

4. Consider a single observation of a random variable having an exponential distribution A. Recall
that
Sx(=) = je,2> 0.
fx(x) =
We have a hypothesis test:
Ho : A=2
H1 : A= 1.
The rejection region is C = {X < K}.
(a)
Decide K so that the test has size a.
(b)
Compute the probability of type II error of this test.
