Consumption of alcoholic beverages by young women of drinking age has been increasing in the United Kingdom, the United States and Europe. Data consistent with the finding reported are shown for a sample of 20 European women.
266, 170, 164, 93, 82, 222, 102, 0, 199, 115, 113, 93, 174, 130, 171, 110, 97, 169, 0, 130
Assume the population is roughly symmetric, construct a 95% confidence interval for the mean annual consumption of alcoholic beverages by European young women.
