Chapter 10, Problem 10.106(choose chapter or problem)
Let Y1, Y2,..., Yn denote a random sample from a normal distribution with mean (unknown) and variance 2. For testing H0 : 2 = 2 0 against Ha : 2 > 2 0 , show that the likelihood ratio test is equivalent to the 2 test given in Section 10.9. Construct a likelihood ratio test of the hypothesis that the fractions of voters favoring candidate A are the same in all four wards. Use = .05. Ward Opinion 1 2 3 4Total Favor A 76 53 59 48 236 Do not favor A 124 147 141 152 564 Total 200 200 200 200 800
