3 A useful technique [35 points] Prove the claim on slide 16. Be specific about the values of the constants C1, C2 you use in your proof, where Var [X] t = C1 log - , k = C2 2E X]2 .A useful technique Theorem: Let X be an unbiased estimator of a quantity Q. Let {Xijie,je[k] be a collection of independent RVs with X, distributed identically to X, where Var[ X] t = 0 log , k = 0 E 2 EX2 1 k Let Z = medianic[t] k E Xij. Then, Pr(| Z - Q) > EQ)
