A reporter for a large sports television network wants to determine if "homefield advantage" is dependent upon the sport. He collects data from a sample of games played in the four major professional sports in the country, and he records the number of home team wins and visiting team wins for these games. Use the 0.10 significance level to test the claim that home/visitor team wins are dependent on the sport. Identify the correct HYPOTHESES used in a hypothesis test of the claim.

• a. H₀: p_basketball= p_baseball= p_hockey= p_football H₁: At least one of these proportions is different than the others
• b. H₀: p_basketball= 0.641, p_baseball= 0.53, p_hockey= 0.538, p_football= 0.576 H₁: At least one of these proportions is different than the distribution in H₀.
• c. H₀: The sport and the homefield advantage are independent. H₁: The sport and the homefield advantage are dependent.
• d. H₀: The sport and the homefield advantage are dependent. H₁: The sport and the homefield advantage are independent.
