: Principal Larissa Weems and Mayor Walker are interested in finding out whether
exposure to outcasts (e.g., vampires, werewolves, sirens, ghoulies, etc.) influences the liking of
outcasts among normies of high school age. They want to know if normie student visitors to
Nevermore Academy will change their liking for outcasts after a week-long stay at Nevermore
Academy. They record the ratings of ten normie student visitors, from 1 (dislike very much) to 7
(like very much), before their week-long stay at Nevermore Academy and again one week later.
Prior research suggests that liking of outgroup members is normally distributed in the
population. Help Principal Weems and Mayor Walker to test whether the intervention of time
spent at Nevermore Academy changed the normie student ratings of outcasts. Use ā = 0.05. How to post a question to be solved by experts? Participant Before Visit One Week Later
