An association studies the ethnicity of moviegoers to understand changes in the demographics of moviegoers over time. The accompanying table displays the numbers of moviegoers (in millions) classified as to whether they were Hispanic, African-American, Caucasian, and Other for a certain year. 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. The distribution of moviegoers is V the population as a whole. V seem to buy proportionally more tickets than the other ethnic groups and V appear to buy proportionally fewer tickets. V appear to go to the movies more often (proportionally buy more tickets) than the other ethnic groups.
