23.A recent sales study indicated that consumption of seafood dishes in Bay City restaurants has increased by 30 percent over the past five years. Yet there are no currently operating city restaurants that specialize in seafood. Moreover, the majority of families in Bay City are two-income families, and a nationwide study has shown that such families eat significantly fewer home-cooked meals than they did a decade ago but at the same time express more concern about eating healthily. Therefore, a new Bay City restaurant specializing in seafood will be quite popular and profitable.
A、如果基数比较小,增长30%没有意义。即使有意义也是在过去的5年,并不表示今后也会如此。即使今后也是如此,人们也未必喜欢到海鲜专店去吃海鲜。人们可能觉得在那些饭馆偶尔搭配海鲜会更有味道,而不是就是喜欢吃海鲜。B城现在没有海鲜专店可能从侧面反映了这个问题。
B、全国调查,调查类错误,抽样是否随机化。即使随机化,也是全国的,未必适用于B城。即使适用,人们不喜欢在家吃饭和喜欢更健康的食品,并不表示人们就喜欢吃海鲜,这之间不存在必然联系。
C、即使人们都会选择出去吃海鲜,该海鲜专店也未必会盈利。经济学常识,品牌成本。
