Explanation of Solution

Given:

1000 students take such a test.

Pscored 63 in test.

Calculation:

Percentile value tells us about the scores below that value. For example, ${60}^{\text{th }}$ percentile tells that $60\%$ of scores are below ${60}^{\text{th }}$ percentile. It is given that 1000 took a test and Peter got score of 63 which placed him at the ${73}^{\text{rd }}$ percentile. This implies that $73\%$ of scores are below score 63 (or) Pete did better than about $73\%$ of the test takers.
