Suppose that the mean of the annual return for
common stocks from 2000 to 2012 was 14.37, and
the standard deviation of the annual return was
35.14. Suppose also that during the same 12-year
time span, the mean of the annual return for
long-term government bonds was 0.6, and the
standard deviation was 2.1. The distributions of
annual returns for both common stocks and
long-term government bonds are bell-shaped and
approximately symmetric in this Assume that these
distributions are distributed as normal random
variables with the means and standard deviations
given previously.
