  The table summarizes information in several categories about the 9 stores in a small grocery chain. The table also includes chain- wide averages where appropriate.

  For each of the following statements, select True if the statement can be verified to be true based on the information provided. Otherwise, select False.

  1. In each store whose average customer age falls between 34 and 36, the number of self-check express lanes is above average.

  2. There is a negative correlation between the number of self-check unlimited lanes and the average customer age.

  3. Stores in this table that have fewer self-check express lanes than the chain-wide average are less likely to have restaurants than stores that have more self-check express lanes than the chain-wide average.

  正确答案

  TRUE TRUE FALSE

  题目解析

  第一题:每个顾客平均年龄在34-36岁的商店里,self-check express lanes的数量超过平均数。

  True A F两店满足年龄要求,self-check expresslanes的数量都是8,超过平均数6.89。

  第二题:self-check unlimited lanes的数量和平均顾客年龄呈反比(Negative Correlation其实是负相关性,与反比并不相同,这里的提法是为了方便理解)。

  True 把所有self-check unlimited lanes数量不为0的商店从小到大排列一下,再对应填入平均年龄数据,就可以看到数据的整体趋势的确是反比,所以正确。

  第三题:表格中self-checkexpress lanes数量低于平均值的店拥有餐厅的情况也更少。

  False self-check express lanes数量低于平均值的店为C,H和I,这三家店都是拥有餐厅的,所以不成立。
