Hypothesis testing will consist of four hypothesis tests which you need to complete. each test will require the following: Type of Test: Null Hypothesis: Alternate Hypothesis: SE: Test Statistic: P-value: Decision: Sentence:
A. P (win/regular) = 0.82 P (win/prevent) = 0.64 Conclusion: You are more likely to win by playing prevent defense. B. P (win/regular) = 0.33 P (win/prevent) = 0.67 Conclusion: You are more likely to win by playing prevent defense. C. P (win/regular) = 0.82 P (win/prevent) = 0.64 Conclusion: You are more likely to win by playing regular defense. D. P (win/regular) = 0.33 P (win/prevent) = 0.67 Conclusion: You are more likely to win by playing regular defense.
