    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.
