In the context of the study on the advantage of the team winning the coin toss in NFL games: The null hypothesis ( �� ) is that winning the coin toss does not give a team an advantage, and the alternative hypothesis ( �� ) is that winning the coin toss does give a team an advantage. Type I error occurs when we reject the null hypothesis ( �� ) when it is actually true. In this study, a Type I error would be concluding that the team winning the coin toss has an advantage when they do not. Type II error occurs when we fail to reject the null hypothesis ( �� ) when it is actually false. In this study, a Type II error would be failing to conclude that there is an advantage for the team winning the coin toss when there actually is one. It is important to balance the risks of making Type I and Type II errors in hypothesis testing by choosing an appropriate level of significance and power of the test.
