A researcher is interested in comparing the usage of bank debit cards by consumers in
rural (r) and urban (u) areas. Each year for the past five years, she has surveyed 500
individuals (one’‘half urban, one’‘half rural) randomly selected from across the United

groups with regard to usage. The results of the current study indicate that people in
urban areas use bank debit cards 12 times per month on average (xu), while those in
