Vlad [161]

Answer:

Step-by-step explanation:

To calculate the 99th percentile you must  order scores from least to greatest, and the one that occupies the position that corresponds to 99% of n-scores is the 99th percentile.

The 99th percentile of a set of observations ( in this case, exam scores) is a value such that 99% of the observations are less than or equal to him and the remaining 1% is greater than or equal to him.

If he is now in the 84% is because there are some people that took the exam in February that are better than him, they had better scores and then, 84% of the observations are less than or equal to him and the remaining 16% is greater than or equal to him.

Before there were only 1% scores that were better than his or her score. Now, there are 16% scores that are better, then people got better scores in the February exam, compared to your friend's score.
