Answer 1

Kevin scored at the 60th percentile on a test given to 9840 students.

Percentile of Kevin = 60th

Number of students = 9840

The objective is to find the number of students, those scored lower than Kevin

Let x be the number of students, those scored lower than Kevin.

The formula for the percentile is as follows;

`\text{ Percentile=}\frac{Number\text{ of students who scored lower than kevin}}{Total\text{ number of students}}*100`

Substitute the value;

`\begin{gathered} \text{ Percentile=}\frac{Number\text{ of students who scored lower than kevin}}{Total\text{ number of students}}*100 \\ 60=(x)/(9840)*100 \\ x=(9840*60)/(100) \\ x=5904 \end{gathered}`

Therefore, there are 5904 students who cored lower than Kevin out of 9840

Answer : 5904 students
