Explanation:
Variance (σ2) is the average of squared difference from mean.
Mean is M=2+4+6+8+105=305=6
Variance is σ2=(26)2+(46)2+(66)2+(86)2+(106)25
=16+4+0+16+45=405=8
So the variance is 8 [Ans]

Mean, x=2+4+6+8+105=305=6
Variance =1n(xix)2
=15ft{(26)2+(46)2+(66)2+(86)2+(106)2right}
=15ft{16+4+0+4+16right}=15×40=8
