Paper Details
Suppose that X1, . . . , Xn form a random sample from the Poisson distribution with unknown mean ?, and suppose that it is desired to test the following hypotheses:
H0: ? ? 1,
H1: ? < 1.
Suppose also that the sample size is n = 10. At what levels of significance ?0 in the interval 0 < ?0 < 0.03 do there exist nonrandomized UMP tests?
