9.02

9.08

9.06

Find the mean which I will call 9.04 but you need to calculate it. 9.04 is an estimate only.

Then 9.04-9.04 = 0

9.02-9.04 = 0.02 (disregard the signs)

9.08-9.04 = 0.04

9.06-9.04 = 0.02

Now find the mean of those differences. That will be (0.00 + 0.02 + 0.04 + 0.02))/4 = ?0.065 and round to the correct number of significant figures.
