A sample survey of 56 discount brokers showed that the mean price charged for a trade of 100 shares at $50 per share was $33.82. The survey is conducted annually. With the historical data available, assume a known population standard deviation of $14. a. Using the sample data, what is the margin of error associated with a 99% confidence interval (to 2 decimals)?
