Question 8Let X1, X2,„X9 be nine independent and identically distributed random variables from a binomialdistribution with five trials and unknown probability of success. Which of the following is anunbiased estimator of p.Note that due to lack of subscripts in the answers X1 denotes X1.O (X1 + X2 ++ X9)/45O (X1 + X2 +.. + X9)/5(X1 + X2 ++ X9)/9...X1 + X2 + ... + X9
