Question Two Suppose X1, . .., An are a random sample from a population with density for x > 0 where a > 0 is the shape parameter and B > 0 is the scale parameter. a) Which of the following is a two dimensional sufficient statistic for 0 = (o, B)'. Consider applying the Neyman- Fisher Factorization Criterion. T = (T1, T2) = (X,ex ) O T = (T1, T2) = (CXineEr,x ) O T = (T1, T2) = ( Ex. >x?) O T = (11, T2) = (II X. Ex.) i=1 i= 1
