Interval estimation and statistical inference
... That is, a 95% prediction interval is ($11400, $105440). Note this interval is not symmetric (it is “centered” at the geometric mean of the incomes, 101.54 = $34674), as it reflects the inherent long right tail in the incomes themselves. The interval is wide, but reflects the actual income distribut ...
