Mr. Acosta, a sociologist, is doing a study to see if there is a relationship between the age of a young adult (18 to 35 years old) and the type of movie preferred. A random sample of 93 adults revealed the following data. Test whether age and type of movie preferred are independent at the 0.05 level.

(e) Interpret your conclusion in the context of the application. O At the 5% level of significance, there is sufficient evidence to conclude that age of young adult and movie preference are not independent.
