    For the best estimate we can see that 18 appears to be somewhat an outlier.

    Therefore we can dismiss this as an oulier in the mean and range calculation.

    So the Best Estimate Mean is (22+20+24+21+23) / 5=22

    And the Best Estimate Range is 24-20=4

    However the Normal Range would be 24-18=6
