Chapter 12, Problem 1CP

To determine

To find :the number after approximately the ${75}^{\circ }$ % data are greater.

Answer to Problem 1CP

the number after approximately the ${75}^{\circ }$ % data are greater is $15$ .

Explanation of Solution

Given : the numbersprovided in the question,

  $15,22,18,14,19,22,30,28,11,25,33$ .

by observing all the numbers, we recognize that $11$ is the smallest number so after that number all numbers are greater.

So after $15$ the data approximately ${75}^{\circ }$ % greater. Because after that number there is 9 numbers which are greater, so this is approximately ${75}^{\circ }$ % of total numbers.

Hence,the number after approximately the ${75}^{\circ }$ % data are greater is $15$ .
