Questrom 3 (a) ( x 19) = 0 (1-0 )*- , oxo c, (8) = Im (10) Therefore , f(x 10 ) belongs to the 1-parameter exponential family. (b ) Since fixlol belongs to the 1- howometer exponential family , E [ t(x) ] = 2 xi is Complete Sufficient statistic i = 1 fon o. ( c ) . E ( x cou) ) = 4 (8 ) = 9 You [to] = 4 ( B ) = -20 - 1 do E ( Z X i ) = m 0 2 . 0 Van ( 2 xi ) = 1 - 20 .m (0-0 ) 2Question 2 Let X1, X2, X\" be a random sample from a geometric?) distribution with probability mass function: 6(19)x1 ifo
