Unlike most packaged food products, alcohol beverage container labels are not required to show calorie or nutrient content. the article âwhat am i drinking? the effects of serving facts information on alcohol beverage containersâ (j. of consumer affairs, 2008: 81-99) reported on a pilot study in which each of 58 individuals in a sample was asked to estimate the calorie content of a 12-oz can of beer known to contain 153 calories. the resulting sample mean estimated calorie level was 191 and the sample standard deviation was 89. does this data suggest that the true average estimated calorie content in the population sampled exceeds the actual content? test the appropriate hypotheses using p-value at significance level .001.
