Returning to the Super Bowl example, imagine you draw a sample of 20 teams (N = 20) rather than 12. For this situation,

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

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

c. What decision would you make about the null hypothesis if you found 16 of the 20 teams that won the coin flip also won the game?

d. If you had found that 13 of the 20 teams that won the coin flip also won the game, would this support or not support the research hypothesis?
