To find the t-score, we use the formula: t = (raw score - mean) / standard deviation. Plugging in the values, we get: t = (86 - 88) / 4 = -0.5. To find the z-score, we use the formula: z = (raw score - mean) / standard deviation. Plugging in the values, we get: z = (86 - 88) / 4 = -0.5. Therefore, the best choice is B.
