<span>Given:
check written year 1 year 2 year 3
yes 225 175 125
no 275 325 375
</span><span>The expected number of shoppers who pay by check in year 1 if there is no difference in the proportion of shoppers who pay by check among the three years is 175.
Each year has 500 customers, and its proportion of customers paying in check gradually decreased from 45% to 25%. If there is no difference in proportion, I am assuming that the data is averaged. Thus, (225+175+125) / 3 = 525 / 3 = 175.</span>
