Consumption of alcoholic beverages by young women of drinking age has been increasing in the United Kingdom, the United States, and Europe. Data (annual consumption in liters) consistent with the findings reported in The Wall Street Journal article are shown for a sample of 20 European young women.
76 82 199 174 97
170 222 115 131 169
164 96 118 171 0
93 0 93 110 240
Assuming the population is roughly symmetric, construct a 95% confidence interval for the mean annual consumption of alcoholic beverages by European young women.
