15 As part of the marketing group of a film company, you are asked to find out the age distribution of the audience of the latest film. You ask questions of customers who exit the theatre. From 500 responses, you find that 49 are younger than 6 years old, 87 are 6 to 9 years, 165 are 10 to 14, 25 are 15 to 21, and 174 are older than 21. a) Make a frequency table of these categorical data. b)Make a relative frequency table. c) Make a bar chart using counts in the frequency table. d) Would a bar chart of relative frequencies look any different? e) Make a pie chart. 16 17 Write a few sentences summarizing the distribution demonstrated by your charts and tables. In addition to age grouping information, the audiences interviewed were also asked if they had seen the movie before (Never, Once, More than Once). never once under 6 6 to 9 42 10 to 14 15 to 21 over 21 62 90 20 152 4 more than once 3 21 4 41 5 34 0 17 5 a) Find the marginal distributions of their previous viewing of the movie. Margin means total. Create a new column labeled "total". b)Verify that the marginal distribution of the ages is the same as that given previously. Create a bottom row labeled "total". Continue with the data from question 17 18 c) Find column percentages. d) Looking at these percentages, does the distribution of how many times someone has seen the movie look the same for each age group? What can you assume from these percentages? e) Make a stacked bar chart showing the distribution of viewings for each age level f) What is the percentage of all audience members who are over 21? And what percentage of audience members who saw the movie more than once are over 21? g) If these proportions are not the same, what does that mean with respect to the variables "age" and "frequency of viewing movies"? 15 As part of the marketing group of a film company, you are asked to find out the age distribution of the audience of the latest film.
