Question

A researcher wants to study alcohol consumption at local parties. The researcher is particularly interested in the amount of alcohol consumed at parties where untrained friends or acquaintances mix the drinks (instead of trained bartenders). For this study, a standard drive was defined as 12 oz of beer (5% vol.), 5 oz of wine (12% vol.), 1.5 oz liquor (40% vol.), or 1.5 oz of liquor in a mixed drink (National Institute on Alcohol Abuse and Alcoholism, 2000). Compute the range, the variance, and the standard deviation for these data.
