You sure? Sure… Why wouldn’t it be? SqRt(0.4) = SqRt(4/10) = SqRt(4) / SqRt(10) = 2 / SqRt(10) Then, just to add some irrationality, multiply top and bottom by pi = 2pi / (SqRt(10)*pi) = 2pi / SqRt(10*pi^2)

CFA vs MBA? gets 'em all the time, lol.

Still clueless on your estimates of % of interviewed people who screw it up
