A reader wrote in to the opinion column of a sports magazine to say that his grandfather told him that in ¾ of all baseball games, the winning team scores more runs in one inning than the losing team scores in the entire game. (This phenomenon is known as a “big bang.”) The columnist responded that this proportion seemed to be too high to be believable. An SRS of 190 Major League Baseball games was examined and 98 of them contained the “big bang.” Test the claim at the 5% significance level.
