Question 1 You work in
marketing for a company that produces work boots.
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. Question 2 For any normally
distributed random variable with mean µ and
standard deviation s, the percent of the
observations that fall between µ-2s and µ2s is
closest to _______.
