Chapter CSB, Problem 8.1E

To determine

Find the %age of students drive more than $30miles$ in a day.

Answer to Problem 8.1E

  $25\%$

Explanation of Solution

Given information:

Tyler randomly survey $20$ students at his school to know the miles they drive in an average day,

By box-and −whisker plot.

  

Calculation:

Consider the box-and −whisker plot.

  

There are $5po\mathrm{int}s$ on plot and survey done on $20$ students,

%age of students drive more than $30miles$ in a day is,

  $\frac{5}{20}\times 100=25\%$

Hence, %age of students drive more than $30miles$ in a day is, $25\%$
