Let X have the binomial distribution b(p, n), and consider the hypothesis H : p = p0 at level of significanceα. Determine the boundary values of the UMP unbiased test for n = 10 with α = 0.1, p0 = 0.2 and with α = 0.05, p0 = 0.4, and in each case graph the power functions of both the unbiased and the equal-tails test.
