A study of crowd-funded projects showed that overall a majority were successful, that is, raised at least the targeted goal amount. In an effort to identify project types that influence success, selected projects were subdivided into project categories (Film & Video, Games, Music, and Technology). Click the icon to view the crowdfunded project data. I. a. Construct contingency tables based on total percentages, row percentages, and column percentages. Complete the following contingency table based on total percentages. Outcome Category Successful Not successful Total Film & Video 15.05% 22.94% 37.99 % Games 5.37% 8.53% 13.89 % Music 16.70 % 19.01 % 35.71 % Technology 5.32% 7.08 % 12.41 % Total 42.44 % 57.56 % 100 % (Simplify your answers. Round to two decimal places as needed.) Complete the following contingency table based on row percentages. Outcome Category Successful Not successful Total Film & Video & 39.63% 60.37% 100 % Games 38.62 % 61.38 % 100% Music 46.77 % 53.23 % 100 % Technology 42.90 % 57.10 % 100 % Total 42.44 % 57.56 % 100 % (Simplify your answers. Round to two decimal places as needed.) Complete the following contingency table based on column percentages. Outcome Category Successful Not successful Total Film & Video 35.47 % 39.85% 37.99% Games 12.64% 14.82% 13.89 % Music 39.35% 33.03% 35.71 % Technology 12.54% 12.31% 12.41 % Total 100 % 100% 100 % (Simplify your answers. Round to two decimal places as needed.) b. Which type of percentage-row, column, or totalis most informative for these data? XA Column percentages are most informative, since they allow the direct comparison of project success for the four categories. B. Row percentages are most informative, since they show the success rate for each type of category. O C. Total percentages are most informative, since the goal is to find a pattern in the overall distribution of successful projects. c. What conclusions concerning the pattern of successful crowd-funded projects can you reach? Of the successful projects, more came from music projects than any other project. Music projects were more likely to be successful than other projects. - Crowdfunded Project Data Category Film & Video Games Music Technology Total Outcome Successful Not successful 17,857 26,857 4,686 10,690 16,922 20,135 4,379 6,838 43,844 64,520 Total 44,714 15,376 37,057 11,217 108,364 Print Done
