Passing the ball between two players during a soccer game is a critical skill for the success of a team. A random sample of passes made by the English and German teams in the 2010 World Cup was drawn, and the number of successful passes in each sample was counted. Is there any difference in accuracy if we assume a level of significance of .01? See data below:

Germany England
# of successful passes 69 71
Total in the sample 76

91

Reject the null, there is no difference in accuracy

Do not reject the null, there is no difference in accuracy
