She plays a classical selection to one group and a modern selection to another. She gives each person an irritability questionnaire and obtains the following: Classical: n = 6, X = 14.69, s² = 8.4 Modern: n = 6, X = 17.21, s² = 11.6 (a) Subtracting C- Mwhat are Ho and H₂? (b) What is tobt? (c) With a = .05, are the results significant? (d) Report the results using the correct format. (e) What should she conclude about the relationship in nature between type of music and irritability? (f) What other statistics should be computed?
