12.81 Planning another emotions study. Scores on an emotional scale were compared for five different cultures in Exercise 12.59 (page 691). Suppose that you are planning a new study using the same outcome variable. Your study will use European American, Asian American, and Hispanic American students from a large university.

  1. (a) Explain how you would select the students to participate in your study.

  2. (b) Use the data from Exercise 12.59 to perform power calculations to determine sample sizes for your study.

  3. (c) Write a report that could be understood by someone with limited background in statistics and that describes your proposed study and why you think it is likely that you will obtain interesting results.
