The Data:
Creative Scores | |||
Red Background | n = 35 | = 3.39 | s = 0.97 |
Blue Background | n = 36 | = 3.97 | s = 0.63 |
1. Example/Problem to Solve: (Use table A-3)
Using the data from this color creativity example, construct a 98% confidence interval estimate for the difference between the mean creativity score for those with a red background and the mean creativity score for those with a blue background.
2. We are 98% confident that the limits -1.05 and -0.11 actually do contain the difference between the two population means.
Because those limits do not include 0, our interval suggests that there is a significant difference between the two means.
3. State the conclusion
