The daily sleep duration among Yale students is
normally distributed with a mean of 8.13 and standard
deviation of 1.87 , you want to use a sample size such that 95% of
the averages fall within plus or minus 15 minutes (0.25 of an hour)
of the true mean of 8.13 , find the smallest number of students you
need to sample??
