 Working with the Neyman-Pearson Lemma.


(a) A sample of size n taken from a normal population with a known variance of σ
2 = 9.7969 is used to
test H0 : µ = µ0 against H1 : µ = µ1 where µ1 > µ0. Use the Neyman-Pearson Lemma to produce
a test statistic and the corresponding most powerful critical region at the α level of significance for a
given α.


(b) Suppose the sample size is n = 49, H0 : µ = 1 and H1 : µ = 3.5. Find most powerful critical region
at the 1% level of significance for testing H0 against H1. ‹en compute the power of the test.
