Annual salary plus bonus data for chief executive officers are presented in a magazine Annual Pay Survey. A preliminary sample showed that the standard deviation is $673 with data provided in thousands of dollars. How many chief executive officers should be in a sample if we want to estimate the population mean annual salary plus bonus with a margin of error of $100,000? (Note: The desired margin of error would be E=100 if the data are in thousands of dollars.)...
