Question

if the highest number in a range is 40 and lowest is 22, an estimate of the standard deviation is 3.

Answer 1

By using standard deviation, it can be concluded that

The given estimate of standard deviation = 3 is not true

What is Standard Deviation?

At first, it is important to know about variance.

Variance is the sum of the square of deviation from mean divided by the total number of observations. Standard Deviation is the square root of variance.

Highest number = 40 and lowest number  = 22

Range = 40 - 22 =18

Standard deviation = $18 \div 4$

Standard deviation = 4.5

So the above statement is false
