Describe, for each of the two characteristics, the relation between skilled and unskilled growth managers that would support Byrne's conclusion.

Solution:

The cost of a Type I error is retaining a manager without skill, as opposed to the cost of a Type II error which is firing (or not hiring) a manager with skill. The cost is driven by the sample size, shape, mean, and dispersion of the return distributions of the skilled and unskilled managers within the peer universe. The smaller the difference in sample size and distribution mean and the wider the dispersion of the distributions, the smaller the expected cost of the Type I or Type II error.
