Determine the test statistic for the interaction effect.

In a study, a random sample of 20 adults rated the effectiveness of advertisements. Each adult rated an advertisement that lasted 30 or 60 seconds. The block design
in the accompanying table shows these ratings (on a scale of 1 to 5, with 5 being extremely effective). Use a = 0.05 and a technology tool and the given block design to
perform a two-way ANOVA test.
