how to calculate Q13 and Q15?

 

Now consider the z test using independent samples. We pretend that each team's wins and losses are independent random samples with replacement from 0-1 boxes in which the fraction of ones represents the probability that that team wins each game it plays. The number of tickets labeled "1" in the sample is the number of games the team wins. Problem 5 The sample percentage of games won by Stanford is (Q12) 0.94 On the assumption that the null hypothesis is true, the bootstrap estimate of the standard error of the sample percentage of games won by Stanford is (Q13) (Hint: if the null hypothesis is true, then with the simplifications we made it is as if the teams independently draw at random with replacement from the same box of tickets. What percentage of the tickets in that box would you estimate to be labeled "1?") The sample percentage of games won by Cal is (Q14) 5 On the assumption that the null hypothesis is true, the bootstrap estimate of the standard error of the sample percentage of games won by Cal is (Q15)
