An athlete has just been drafted by both the NBA to play professional basketball and by MLB to play professional baseball. In order to assist him in deciding which offer to pursue, he enlists a statistician to test whether or not NBA athletes or MLB athletes are more likely to suffer a concussion. The statistician believes that athletes in both leagues are equally likely to suffer a concussion, but decides to test this belief at the alpha = 0.05level of significance using a confidence interval. Let p N represent the proportion of NBA players that have suffered from a concussion and represent the proportion of MLB players that have suffered from a concussion.(Round your results to three decimal places ) 1. Which would be correct hypotheses for this test? O H 0 :p N =p M ,H 1 :p N p M OH H O :p N ne p M ,H 1 :p N >p M O H 0 :p N =p M ,H 1 :p N ne p M 2. If we are going to test this using a confidence interval, which confidence interval should we construct? O 80 % 90% 97.5 % 95% In a random sample of 295 NBA players, 208 were found to have suffered from at least one concussion. In a random sample of 311 MLB players, 258 were found to have suffered from at least one concussion. 3. Construct the confidence interval: < PN-PM<
