You need to estimate the mean number of travel days per year for
outside salespeople. The mean of a small pilot study was 150 days,
with a standard deviation of 46 days.
If you must estimate the population mean within 8 days, how many
outside salespeople should you sample? Use the 95 percent
confidence level. (Round up your answer to
the next higher whole number.)
