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 expect that researcher A's 95% prediction interval around y A to be, in general, A) narrower than researcher B's 95% prediction interval around y B. B) 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. C) wider than researcher B's 95% prediction interval around y B. D) the same as researcher B's 95% prediction interval around y B.
