TradeLine, is an online stock-trading service. To estimate the average number of trades made last month by TradeLine's clients, you take a simple random sample of 25 clients and find the average number of trades in the sample is 42.7. Since you do not know the population standard deviation, you calculate the sample standard deviation as 11.6. Assume that the population is normally distributed. Show the appropriate 99% confidence interval for the average number of trades for all of TradeLine's clients.
