The owner of a winery is wondering whether the average purchase made by visitors to her winery differs according to age. She asks the cashiers to keep track of a random sample of purchases by customers in three age groups: under 30, 30-50, over 50. Because there is no good reason to ask a customer his or her age, the cashiers guess which age group a customer belongs to (and if they do not guess accurately, the research may not be helpful). Eventually, data from about 50 purchases made by customers in each of the age groups are collected. Do these data meet the required conditions for one-way ANOVA?
