Returning to the Super Bowl example discussed earlier in this chapter, imagine that you found 13 of 18 teams that won the coin flip went on to win the game.

a. State the null and alternative hypotheses (H₀ and H₁).

b. Identify the critical values for α = .05 and state a decision rule.

c. Make a decision about the null hypothesis.

d. Does the result of your analysis support or not support the research hypothesis that winning the coin flip increases a team’s chances of winning the game?
