Also included are the numbers for the general population and the number of tickets sold. Complete parts a and b below. E Click the icon to view the table of results. a) Construct the conditional proportions of Ethnicity for all three groups: the entire population, moviegoers, and ticket holders. IT Caucasian Hispanic African-American Other Population 0% Moviegoers % % Tickets % D% % (Round one decimal place as needed.) b) Write a brief description of the association between population groups and Ethnicity.
