Question

# Answer the following with the help of the data:

There is a factory which produces cars. The following data shows the no. of cars produced in 8 months.

20, 25, 15, 35, 40, 55, 50, 0

What is the standard deviation when the variance is 25?

- 225
- 196
- 169
- 256

## The correct answer is: 256

### We have if variance is then standard deviation is .

Here variance is 25 then standard deviation is 5.
