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?

- 4
- 3
- 5
- None of the above

## The correct answer is: 5

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

Here variance is given i.e. .

It imply standard deviation is 5.
