Aa Aa A sports ?nalogy for hypothesis tests tn recent years, professional sports have incorporated the use of instant replay in order to dispute I Football League (NFL) a head coach is allowed to challenge the referees' decision twice per game. tn order for the erees to reverse their original decision, the instant replay must exhibit dear evidence to the contrary before completely catching the ball, and the coach challenges the referees decision The referees will review all available contradict the original call, the play will remain ruled as a complete pass. the referes rule that a pass was caught in bounds. The head coach of the opposing team beleves the player stepp evidence (video taken from different camera angles) and make a decision. If there is evidence beyond a reasonable doubt that their original call was incorrect, the play willbe called an incomplete pass. However, if there is no clear evidencoe o reject the null hypothesis in a hypothesis test. The process Notice the similarity between the decision to change a call and the decision t involves collecting convincing evidence that the original call or the null hypothesis is not true. The referee only replay exhibits clear evidence to the contrary, just as a researcher only rejects the null hypothesis if the study resu the contrary. In both cases, not changing the call and not rejecting the null hypothesis doesnt mean was correct; it means that not enough evidence was provided to the contrary rejects the call if the instarnt s if the study results provide clear evidence to the null hypothesis that the original call or and the alternative To formulate the process as a hypothesis test, the null hypothesis is that the player hypothesis is that the player The testing procedure then assumes that the player with a goal of determining whether there is enough evidence to infer that the player caught the ball in bounds caught the ball out of bounds After the referces review video of all referces make?

Explanation / Answer

To formulate the process as a hypothesis test, the null hypothesis is that the player caught the ball in bounds. and the alternate hypothesis is that the player caught the ball out of bounds. The testing procedure then assumes that the player caught the ball in bounds , with a goal of determining whether there is enough evidence to infer that the player caught the ball out of bounds.

Correct Choices: ( Note: Evidence is collected to support alternate hypothesis. So choice having "out of bounds" phrase must be correct.)

c. Conclude that they have convincing evidence to support the hypothesis that the player caught the ball out of bounds.

d. Conclude that they do not have convincing evidence to support the hypothesis that the player caught the ball out of bounds.

Type I error:

In this case, a type I error corresponds to the referees concluding that they have convincing evidence to support the hypothesis that the player caught the ball out of bounds when the player actually caught the ball in bounds.

Type II error:

In this case, a type II error corresponds to the referees concluding that they do not have convincing evidence to support the hypothesis that the player caught the ball out of bounds when the player actually caught the ball out of bounds.
