Given x = 3, the scores corresponding to x = 3 are 65 and 71. The best predicted value for y given x = 3 is the average of these scores, which is (65 + 71) / 2 = 68. However, since 68 is not an option and the closest option is 71, A) 71 is chosen as the best predicted value based on the available options.
