Answer: Mean= (-) 9.5
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 = [tex]\frac{\text{Sum of observations}}{\text{Total no. of observations}}[/tex]
So it becomes ,
Mean = [tex]\frac{-11-22-2-3}{4}[/tex]
= [tex]\frac{-38}{4}[/tex]
= (-)9.5
∴ Mean of given set of numbers = (-) 9.5
