It is a type of mathematical convolution If we represent the original time series by y then a twosided moving average of the time series is given by 1 t 1 k 2 n k Thus 1 z forms a new time series which is based on averages of the original time.

Since 0.329 is exactly two standard deviations above the mean, we know that about 95% of batting averages will be between 0.193 and 0.329. Since the curve is symmetric, half of the remaining 5%, or 2.5% should be above 0.329.
