Question:
=+5.7. A random sample of 10 observations is drawn from a normal population with mean m and variance 1. Instead of a normal-theory test, the ordinary sign test is used for H0: m ΒΌ 0, H1: m > 0, with rejection region K 2 R for K 58.
(a) Plot the power curve using the exact distribution of K.
(b) Plot the power curve using the normal approximation to the distribution of K.
