Step 1: Content Introduction

The formula for calculating percentile is:

$\frac{x + 0.5 y}{n} (100)$

Here,

x is number of data values counting from the bottom of the data

y is number of data values which are same

n is total number of data values.

Step 2: Content Explanation

The rank $37$ was only given to Jesse, it means that $x = 143, y = 1$

$= \frac{143 + 0.5 (1)}{180} (100) = 80$
