2. You are planning to test the effect of music therapy on chronic pain intensity among a single group of older adults in long-term care. What statistical test will be appropriate to determine if a significant difference on pain intensity is present before and after treatment in a single group?

a. One-way ANOVA

b. One-sample t-test

c. Independent t-test

d. Dependent t-test

Give answer with rationale for the correct answer

3. You find that there is a significant mean difference among three different ethnicity groups on risk for falls in a nursing home and want to find out which group differs specifically from which group. What procedure will help you determine such differences?

a. Bonferroni test

b. Levine’s test for homogeneity
