Transcribed Image Text: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.
