5. Suppose X a single observation from a population with a Beta(0,1) distribution. (a) Suppose we want to test Ho :0 <1 against H :0>1 an we use a rejection region of X > 1/2. Find the size and power function for this test. Sketch the power function. (b) Now suppose we want to test H, :0 = 1 against H :0 = 2. Find the most powerful level a test. (Is there a Theorem we can use?) (C) Is...
Problem H5 Let X be a single observation (n-1) from the following distribution: f(rle)-o elsewhere NOTE:XBeta(0, 1) The following two hypotheses are being tested: 110 : e-2 vs Ha : ?-1. (a) Draw a graph of f(z | ?) when (i) Ho is true and when (ii) H. is true. Put both graphs on the same plot. Explain why a rejection region of the form (X<k) makes intuitive sense (b) Find k, so that the test has level a 0.05....

3. You will have just a single observation of X on which to base your choice between Ho: X has a Normal distribution with mean u = 5 and standard deviation o = 2 а VS. H1:X has a Binomial distribution with n =25 and p = 0.20. Consider the rejection rule "Reject Ho if X is an integer" Find a P(Type I Error) and B = P(Type II Error). Justify your answer.
f(x θ)-(1-0)0' i , X 1, 2, θ 6-(01) and 4.1 Consider one observation from the p.d.f let the prior pd.f. λ on (0,1) be the 110, 1) distribution. Then, determine: (i) The posterior pdf. of θ, given x-x. ii) The Bayes estimate of 6, by using relation (15). The Bayes estimate Ολ(XI, , x.) defined in relation (14) can also be calculated thus (15) where h(θ , , x ) is the conditional p di of θ given X-X,...
