A statment that could not be true include the following: A. The missing number is 11

In Mathematics and Statistics, a range is the difference between the highest number and the lowest number contained in a data set.

In Mathematics and Statistics, the range of a data set can be calculated by using this mathematical expression;

Range = Highest number - Lowest number

From the given data set, we have:

Range = 18.

Lowest number = 12.

Highest number = 30

By substituting, we have:

Range = 30 - 12

Range = 18

Assuming the missing number is 11, it means that the lowest number becomes 11 and then, the range would have to change from 18 to 19;

Range = 30 - 11

Range = 19 (False).

Complete Question;

On the board, your teacher shows an example of finding the range.

One of the numbers is erased, leaving what is shown.

Which of the following could NOT be true?

A: The missing number is 11

B: The missing number is 20

C: The missing number is 25

D: The missing number is 30
