If a portfolio has high variance, then the arithmetic average will be (much greater than, slightly greater than, the same as, slightly less than, much less than) the geometric average

High standard deviation will result in a geometric average that is (much greater than, slightly greater than, the same as, slightly less than, much less than) the arithmetic average.

In a risk-free portfolio, the geometric average will be (much greater than, slightly greater than, the same as, slightly less than, much less than) the arithmetic average.
