The table below looks at data from a study that manipulates both
1. text color (red and blue) and
2. text bold-facing (normal or bold-faced)
on readability.

Based on those data, what main effects do we have? (Assume, for this exercise, that any differences are statistically significant. Note, however, that we would have to do statistical significance tests to find out which, if any, of the observed differences between conditions were reliable differences.)
