The accompanying table lists the lengths, in minutes, and star ratings of televised movies rated 18 +. Use a 0.05 significance level to test whether there is any difference in movie length based on star rating. Based on the results, does it appear that bad adult-rated movies are longer than good ones, or does it just seem that way?

Use the Kruskal-Wallis test.
