An athlete has just been dealted by both the NBA to play professional basketball and by to play professional baseball, In order to assist him in deciding which offer to pursue, he enlists a statistician to 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 = 0.05 level of significance using a confidence interval. Let PN 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 ne p M O H O :p N ne p M H 1 :p N >p M l 0 :p N =p M ,H 1 :p N <p M O H 0 :p N =p N ,H 1 : mathfrak p N >p M O
2. If we are going test this using a confidence interval, which confidence literval should we construct? 95 % 80 % 90 % 97.5\%
In a random sample of 275 NBA players , 195 were found to have suffered from at least one Concussion. In a random sample of 191 MLB players, 129 were found to have suffered from at least one concussion
3. Construct the confidence interval : Box<p N -p M < Box
solve 2 and 3
