Let T1 and T2 be two independent waiting times for this distribution. Find expected time between each call and variance. (E(T) and V(T)) Find the probability for both T1 and T2 to be greater than one.Let X1, X2, X3 be a random sample from a distribution with p.d.f. f(x; 8) = e-(-0) I(8,00) (). Here we use the indicator function of set A defined by I4(æ) = 1, when a E A, zero, elsewhere. Let Y be the first order statistic and let Y be the third order statistic. Then, Select one: O a. Y is sufficient and Y is sufficient. O b. Y is sufficient and Y is not sufficient. O c. Y is not sufficient and Y, is not sufficient. O d. Y, is not sufficient and Y, is sufficient.
