# Data

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
