28. To generalize the results of the preceding problem to the testing of H: 1 vs. K : {1o, 8 E w}, assume: (i) There exists a group G that leaves H and K invariant. (ii) Gis transitive over w. (iii) There exists a probability distribution Q over G which is right-invariant in the sense of Section 4 Determine a UMP invariant test, and show that it is both maximin against K and admissible.
