  Quality control has sent you a memo detailing the
  length of time before the boots wear out under
  heavy use. They find that the boots wear out in
  an average of 208 days, but the exact amount of
  time varies, following a normal distribution with
  a standard deviation of 14 days. For an upcoming
  ad campaign, you need to know the percent of the
  pairs that last longer than six months-that is,
  180 days. Use the empirical rule to approximate
  this percent.
