Question:
Table 8.3 shows the three-point shooting, by game, of Ray Allen of the Boston Celtics during the 2010 NBA (basketball) playoffs (e.g., he made 0 of 4 shots in game 1). Commentators remarked that his shooting varied dramatically from game to game. In game i, suppose that niyi = number of three-point shots made out of ni attempts is a bin(ni, ????i) variate and the {yi} are independent.
