A small town has a population of 15,000 people. Among these 1,500 regularly visit a popular local bar. A sample of 225 people from those who regularly visit the bar is surveyed for their annual expenditures in the bar. It is found that on average each person who regularly visits the bar spends about $2000 per year in the bar with a standard deviation of $196. Construct a 99 percent confidence interval around the mean annual expenditure in the bar.
