claim: cheating exists because of incentive. levitt and dubner support the claim with the reason: sumo wrestlers who win eight or more matches earn a higher rank than those who do not. which evidence supports this reason? a wrestler with ten victories would not throw a match because of the overall incentive to win. the actual win percentage for 7 - 7 wrestlers is higher than the predicted win percentage.
Answer
# Brief Explanations:
The claim is about cheating due to incentive. The reason is sumo wrestlers with more wins get higher rank. The evidence that the actual win - percentage for 7 - 7 wrestlers is higher than predicted implies that there may be cheating (throwing matches) among wrestlers just below the 8 - win mark to help those at 7 - 7 reach 8 wins for the incentive of a higher rank. The first option about a wrestler with ten victories not throwing a match doesn't directly support the idea related to the 8 - win incentive for cheating.
# Answer:
The actual win percentage for 7–7 wrestlers is higher than the predicted win percentage.
