+ve review of 40% movies: Efficiency higher for S : Most people like movies as S reviewed compared to what K reviewed
Negative review of 60% movies: Efficiency higher for K: Most people unlike movies as S reviewed compared to what K reviewed Conclusion: Sartore is a better movie reviewer than Kelly. Which following options give most claim that yes, S is a better reviewer than K.
Quote:
(A) Sartore has technical knowledge of film, whereas Kelly is merely a fan.
Irrelevant Information: It shows no relation with why S efficiency is higher than K . It maybe possible than fan review is more close to audience. It maybe equally possible than a person with technical knowledge can review better.
Quote:
(B) Most of Kelly's movie reviews are unfavorable to the movie being reviewed.
Irrelevant information: It doesn’t give any comparison with review of S.
It may be possible than K total number is smaller than total S. – strengthens the claim
It maybe equally possible that K review movie much higher than S that total number of K matching with audience is much higher than S- weakens the claim
Quote:
(C) One who is apt not to enjoy a particular movie is more likely to realize this by reading a review by Sartore than a review by Kelly.
Seems correct: Efficiency of sarote is higher with a reference , S reference helps t strengthen that S is better than KQuote:
(D) Reading a movie review by Sartore will usually help one to enjoy the movie more than one otherwise would have.
We don’t care how much it would help to enjoy movie. We care more about the number of people can like the movie as predicted by S.
Quote:
(E) Most of the movies that Sartore reviews are also reviewed by Kelly.
Irrelevant information: But I can’t figure out any relation between efficiency of each reviewer. Neither any information is given about a common movie that both reviewed and results were good for S or K
