I want to assess whether different types of movies increase viewers’ stress response. I recruit 24 individuals and randomly assign them into three groups: Frozen (a Disney kids movie), Nightmare on Elm Street (a horror movie), and Fast & Furious (an action movie). After each participant watches their assigned movie, I measure their heart rate. Test, at an alpha of 0.05, whether the type of movie affects heart rate.

a. What is the null hypothesis?

b. What is the alternative hypothesis?
