Construct confidence interval estimate for creativity score-Microeconomics
The Data:
| Creative Scores | |||
| Red Background |
n = 35 |
= 3.39 |
s = 0.97 |
| Blue Background |
n = 36 |
= 3.97 |
s = 0.63 |
1. Problem to Solve:
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.
