... 1. A bowl contains seven marbles of which θ are red while the others are blue. In order to test the null hypothesis θ = 2 against the alternative θ = 4, two of the marbles are randomly drawn without replacement and the null is rejected if and only if both are red. Find the probabilities of Type I an ...
