Xr12-101 According to the American Contract Bridge League (ACBL), bridge hands that contain two fourcard suits, one three-card suit and one two-card suit

(4-4-3-2) occur with 21.55% probability. Suppose that a bridge-playing statistics professor 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 differ from the theoretical probability. If the answer is yes, propose a reason to explain the result.
