Question:

Xr14-86 On reconsidering the experiment in Exercise 14.85, the psychologist decides that the age of the child may influence the attention span. Consequently, the experiment is redone in the following way. Three children of each age (10 year olds, 9 year olds, 8 year olds, 7 year olds, 6 year olds, 5 year olds, and 4 year olds) are randomly assigned to watch one of the commercials, and their attention spans are measured. Do the results indicate that there are differences in the abilities of the products advertised to hold children’s attention?
