Is either of these observations unusually large or unusually small?
O Since the z-score for the smaller observation is larger than 2 in absolute value, the smaller value is unusually small.
Since neither z-score exceeds 2 in absolute value, none of the observations are unusually small or large.
Since the z-score for the larger observation is larger than 2 in absolute value, the larger value is unusually large.
Since both z-scores exceed 2 in absolute value, both of the observations are unusual.
