Based on Pointdexter scoring at the 10th percentile, he is incorrect to say that he outperformed 90% of the class.

Footy's score being at the tail of the distribution means that she is incorrect about being one of the highest in class.

How can the normal distribution on exam scores be explained?

Pointdexter scored better than only 10% of his class because the 10th percentile is a point at the bottom 10% of the scores.

Footy's score being at the tail can either mean that she scored one of the highest scores, or one of the lowest because the tails are for the highest and lowest scores.
