a pipet delivers 9.04,9.02,9.08,9.06 ml in consecutive trials.find the mean volume and the average deviation from the mean

    9.04
    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.
