3) Use the rare event rule and subjective estimates to answer the question. Subjective estimates means you may have to estimate based on your knowledge and experience of life. Claim: people are equally likely to attend (in person) a men's basketball game, men's college football game, men's college hockey game, and women's college volleyball game. A sample of 5000 people revealed that 2843 choose to attend the men's college football game. Choose the best response. a) If the claim is true then approximately % of 5000 would choose to attend each of the four sports. It appears the claim is true. b) If the claim is true then approximately % of 5000 would choose to attend each of the four sports. It appears the claim is false. c) If the claim is false then approximately % of 5000 would choose to attend each of the four sports. It appears the claim is true. d) If the claim is false then approximately % of 5000 would choose to attend each of the four sports. It appears the claim is false. 4) Use the rare event rule and subjective estimates to answer the question. Subjective estimates means you may have to estimate based on your knowledge and experience of life. Claim: people are not equally likely to attend (in person) a men's basketball game, men's college football game, men's college hockey game, and women's college volleyball game. A sample of 5000 people revealed that 643 choose to attend the men's college football game. Choose the best response. a) If the claim is true then something other than % of 5000 would choose to attend each of the four sports. It appears the claim is true. b) If the claim is true then something other than % of 5000 would choose to attend each of the four sports. It appears the claim is false. c) If the claim is false then something other than % of 5000 would choose to attend each of the four sports. It appears the claim is true. d) If the claim is false then something other than % of 5000 would choose to attend each of the four sports. It appears the claim is false.
