Two researchers run identical experiments except researcher A collects twice as many points as researcher B. For a specific value x, researcher A estimates a y value of y'A and researcher B estimates a y value of y'B. We would except that researcher A's 95% prediction interval around y'A to be, in general, (A) wider than researcher B's 95% prediction interval around y'B. (B) narrower than researcher B's 95% prediction interval around y'B. (C) wider than researcher B's 95% prediction interval around y'B or narrower than researcher B's 95% prediction interval around y'B, with equal probability. (D) the same as researcher B's 95%prediction interval around y'B.
