Let Y1 and Y, be two independent observations from a Poison distribution with parameter A> 0. Consider the statistic T = Y +2Y½, Evaluate P{Y1 = 0, Y2 = 1|Y1 +2Y2 = 2} . Using Definition 9.3 (and only Definition 9.3), is T sufficient for A > 0 (explain why yes or why no)? Let Y1, Y2, .., Y, denote a random sample from a probability distribution with unknown parameter 0. Then the statistic U = g(Y1, Y2,., Y,) is said to be sufficient for 0 if the conditional distribution of Y1, Y2, ..., Yn, given U , does not depend on . ....

Hi, I need help with this Math and Stats problem, please. Thank you!

Let Y1 and Y2 be two independent observations from a Poison distribution with parameter 1 > 0. Consider the statistic T = Y+2Y½. Evaluate P{Y1 = 0, Y2 = 1|Y1 + 2Y2 = 2}. Using Definition 9.3 (and only Definition 9.3), is T sufficient for A> 0 (explain why yes or why no)? Let Y1, Y2, ..., Y, denote a random sample from a probability distribution with unknown parameter 0. Then the statistic U = g(Y1, Y2,..., Yn) is said to be sufficient for 0 if the conditional distribution of Y1, Y2,..., Yn, given U , does not depend on 0.
