You wonder whether the ratings of movies that are dramas differ, on average, from the ratings of movies that are comedies. you retrieve the ratings of five comedies and five dramas from the internet movie database (imdb). the ∑r for dramas is 25 and for comedies it is 31. using a p level of 0.05, what conclusion should you draw on the basis of these results? a. given that the smallest of the σr (25) is not equal to or less than the critical value of 2, you fail to reject the null hypothesis. you do not have evidence that the ratings of dramas and comedies differ.
b. given that the smallest u (u = 9) is not equal to or less than the critical value of 2, you fail to reject the null hypothesis. you do not have evidence that the ratings of dramas and comedies differ. c. given that the largest of the σr (31) is greater than the critical value of 2, you reject the null hypothesis. the ratings of dramas and comedies differ.
d. given that the smallest of the σr (25) is greater than the critical value of 2, you reject the null hypothesis. the ratings of dramas and comedies differ.
