      If were known, we’d know that the distribution of responses when X=Xh is normal with mean and standard deviation . Thus, making use of the normal distribution (and equivalently, the empirical rule) we know that if we took a sample item from this distribution, it is very likely that the value fall within 2 standard deviations of the mean.

      Standard Deviation – a statistical measure of the variation between the numbers in a series. For example, the series 8, 10, 12, 14, and 16 has the same average as the series 5, 8, 10, 13, 24 but has a smaller standard deviation since the high and low numbers differ by only 8 while the high and low differ by 19 in the second series.

      Standard deviation is the square root of variance. Ex ante variance calculation: The expected return is subtracted from the return within each state of nature; this difference is then squared. Each squared difference is multiplied by the probability of the state of nature. These weighted squared terms are then summed together. State Ps Rs
