Please answer the second part (iv) (v) (vi) (vii) You and your team have built a chess computer. To investigate how well it performs,you organise a tournament with 100 randomly selected grandmasters (a title given toexpert chess players by the world chess organization FIDE), where your computer willplay each of the grandmasters once, and it is recorded whether the game is a win for thecomputer, a win for the grandmaster, or a draw. For each win against a grandmaster,the computer scores 1 point, and for each draw the computer scores half a point. At theend of the tournament, the chess computer has scored 60 points.i) Identify the population, sample and sample size.ii) Identify a reasonable parameter and parameter space.iii) Using the results of the tournament, give an estimate of the parameter. Explainwhether this is an unbiased estimate.Subsequently, you and your team go away to improve the chess computer. After awhile, you organise another tournament, where the computer will again play 100randomly selected grandmasters. Two members of your team make claims about thenew version of the computer. Alice claims that the new version will perform betteragainst grandmasters than the previous version. Bob claims that the new version willscore an average of at least 0.7 points in games against a grandmaster.iv) Give the null and alternative hypotheses for both Alice and Bob's claims.v) Using the concept of the critical value, explain how Alice's claim can be tested.vi) Using the concept of the p-value, explain how Bob's claim can be tested.Based on the results of the second tournament, you decide there is sufficient evidencefor both Alice and Bob's claims to be accepted. However, you later discover that bothyour tournaments occurred at the same time as the Candidates Tournament (one ofthe most important chess tournaments), and so, each time, your random selection ofgrandmasters excluded the best 10%.vii) With reference to Type I and/or Type II errors, explain how this discovery mightchange your attitude to each of Alice and Bob's claims.
