Based on the scatter plot in Table 3-12, there is a negative relationship between the rating and performance score. This means that as the performance score decreases, we would expect the rating to also decrease. Therefore, a decrease in performance score would be associated with a decrease in rating, as option B suggests. There is no information in the table to predict a change in the performance score of another laptop computer, so option D is not applicable. Options A and C are not supported by the data in the table.
