Use the TI-83/84 Plus results at a 0.05 level of significance to test the claim that home/visitor wins are independent of the sport.

Winning team data were collected for teams in different sports, with the results given in the table below. Use the TI-83/84 Plus results at a 0.05 level of significance to test the claim that home/visitor wins are independent of the sport. Choose the most correct statement from those given below: Fail to reject the null hypothesis that home/visitor wins are independent of the sport. It appears that the home-field advantage does not depend on the sport.

Test the given claim using the displayed software results. Winning team data were collected for teams in different sports, with the results given in the accompanying table (based on data from "Predicting Professional Sports Game Outcomes from Intermediate Game Scores," by Copper, De Neve, and Mosteller, Chance, Vol. $5,$ No. $3-4$ ). The TI- $83 / 84$ Plus results are also displayed. Use a 0.05 level of significance to test the claim that home/visitor wins are independent of the sport. (TABLE CAN'T COPY)

Contingency Tables
Test the given claim. Identify the null hypothesis, alternative hypothesis, test statistic, P-value, or critical value(s), then state the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Use the P-value method unless your instructor specifies otherwise. Use the normal distribution as an approximation to the binomial distribution, as described in Part 1 of this section. Before the overtime rule in the National Football League was changed in 2011 , among 460 overtime games, 252 were won by the team that won the coin toss at the beginning of overtime. Using a 0.05 significance level, test the claim that the coin toss is fair in the sense that neither team has an advantage by winning it. Does the coin toss appear to be fair?
