(a)

To determine

To Describe: what graph reveals about relationship between age group and movie attendance.

Answer to Problem 36E

The graph reveals that as age increases, the percentage of people who attended the movie in last 12 months is decreasing.

Explanation of Solution

The graph reveals that as age increases, the percentage of people who attended the movie in last 12 months is decreasing. As we can see, percentage of people who saw movie in age group 18-24 is 75%, next age group (25-34) is 68% then decreased to 61% in the age group 35-44. For people who are aged 75+ it is around 20%. Percentage of young who saw movie decreased from 80% in the beginning to almost 1/4^th in the old age group aged 75+. This can be interpreted as: - increase in age is associated with less entertainment as people are busy with their jobs, family and health issues as they grow old.
