56. The Chicago Cubs won 73 games and lost 71 in 1995. This was described as a much more successful season for them than 1994, when they won only 49 and lost 64.

a. Based on a binomial model with p1 for 1994 and p2 for 1995, carry out a two-tailed test for the difference.

Based on your result, could the difference in sample proportions be attributed to luck

(bad in 1994, good in 1995)?

b. Criticize the binomial model. Do baseball games satisfy the assumptions?
