Question: More secondhand stores. The study of shoppers in secondhand stores cited in the previous exercise also compared the income distributions of shoppers in the two stores. Here is the two-way table of counts:

Income City 1 City 2

$10,000 to $19,999 52 63

$20,000 to $24,999 69 50

$25,000 to $34,999 22 19

$35,000 or more 28 24

A statistical calculator gives the chi-square statistic for this table as X2 = 3.955. Is there good evidence that customers at the two stores have different income distributions? (Give the degrees of freedom, the P-value, and your conclusion.)
