The sample standard deviation of P/E ratios for stocks listed on the Sydney Stock Ex-change is s = 7.8. Assume that we are now interested in estimating the population mean P/E ratio for all stocks listed on the Sydney Stock Exchange in July 2004. How many stocks should be included in the sample if we want a margin of error of 2? Use a 95% confidence level.
