According to Table 3-11, there is a negative correlation between rating and performance score, which means as the performance score decreases, the rating also decreases. Therefore, a decrease in performance score would be associated with a decrease in rating (choice B). There is no evidence to suggest a predictable change in the performance score of another laptop computer (choice D) or no change in rating (choice C) in response to a change in performance score.
