The answer is negatively skewed. If the mean is 95, then most of the grades are going to be on the right side of a histogram. That means the left tail is the longest, or left-skewed, another name for negatively skewed.

D-right skewed because the majority of the scores will be near 95--which is on the far right side of the range:0-100.

Think about it for a second. Think of your bell curve. If all of the scores are clumped on the high side, wouldn't you say it might be skewed? And on what side of the curve is it skewed?
