Question

Kevin scored at the 65th percentile on a test given to 9800 students. How many students scored lower than Kevin?

Answer 1

It is given that Kevin scored 65th percentile.

To get the number of students who scored lower than Kevin, find 95% of the total number of students, and subtract the result from the total number of students.

This implies:

`9800-(65\%*9800)`

Evaluate the expression:

`\begin{gathered} 9800-((65)/(100)*9800)=9800-(\frac{65}{1\cancel{00}}*98\cancel{00}) \\ =9800-(65*98)=9800-6370 \\ =3430 \end{gathered}`

Hence, the number of students who scored lower than Kevin is 3,430.
