You are interested in studying the effect of different genres of music on the listener's mood. You recruit 32 participants and randomly assign them to listen to either classical, jazz, rock, or pop music for 30 minutes. Their mood is then measured after listening to their assigned genre.

What is the appropriate statistical test?

Using an aplha of 0.05, what is the critical value?

What is the obtained value?

What is your decision about the null hypothesis?

Compute the effect size. Be sure to show your work and interpret the effect.

Conduct a Tukey's post hoc test, and report below which means are different from each other:

a. Classical vs Jazz

b. Classical vs Rock

c. Classical vs Pop

d. Jazz vs Rock

e. Jazz vs Pop

f. Rock vs Pop
