margin of error

44.      A sample survey of 54 discount brokers showed that the mean price charged for a trade of 100 shares at $50 per share was $33.77 (AAII Journal, February 2006). The survey is con- ducted annually. With the historical data available, assume a known population standard deviation of $15.
