An observer wonders if a particular player chooses "Rock" more often than if all three were equally likely to be chosen. To decide, the observer watches this particular player play 15 games and records whether the player chose rock or not rock for each of the 15 games. Of the 15 games played, the player chose "Rock" in 8 of them. Is this evidence that the player chooses "Rock" more often than if all three were equally likely to be chosen in each game
