Answer: Mean= (-) 9.5

Step-by-step explanation:

We have given that ,

The set of numbers are -11, -22, -2, -3

Since we have the numbers which are negative only so the mean will be negative as well.

∴ Mean =
$\frac{\text{Sum of observations}}{\text{Total no. of observations}}$

So it becomes ,

Mean =
(-11-22-2-3)/(4)

=
(-38)/(4)

= (-)9.5

∴ Mean of given set of numbers = (-) 9.5
