A fruit seller claims that customers who purchases lemons are more likely to purchase limes. To test their claim, they tally up the number of customers who purchase these two fruits in a given day. The observed frequencies are given in the 2 x 2 contingency table below. bought lemons did not buy lemons totals 29.867 35.98 38.043 Complete the table of expected frequencies assuming the null hypothesis that buying lemons and buying limes are independent. bought limes did not buy limes totals 27 56 15 34 42 90 bought lemons (expected) did not buy lemons (expected) 21.776 26.133 32.641 29 19 48 (a) Find the expected frequency of customers who bought lemons and limes.
