According to the American Contract Bridge League (ACBL) bridge hands that contain two 4-card suits, one 3-card suit and one 2-card suit (4-4-3-2) occur with 21.55% probability. Suppose that a bridge-playing statistics profess with much too much time on his hands tracked the number of hands over a one-year period and recorded the following hands with 4-4-3-2 distribution (Code 2) and some other distribution (Code 1). All hands were shuffled and dealt by the players at a bridge club. Test to determine whether the proportion of 4-4-3-2 hands differs from the theoretical probability. If the answer is yes, propose a reason to explain the result.
