1. Suppose that we observe data { y; ),_ independently generated from a distribution with probability density function f(y; 0) = 0"(1 + 0 )-1, y = 0, 1, with some 0 > 0.(e) Which of the following is the Wald (ML) test statistic for hypothesis H0 : 6 = 60 for this probability model: ' a. n/QO 90 ' b. ((3 BONE/[u + 60)] ' c. (6 _ 60)n/[l90(1 + 60?] ' d. /[a + 60)] 90
