Paragraph above Figure 16-8

The second of these two sentences is not sufficiently precise and should be revised:

"For bars from Switzerland, the 95% confidence interval on the difference just barely includes the value zero. Thus, there is a slightly bigger than 5% chance that the observed difference between mean ratings of US and Swiss chocolate bars represents nothing more than sampling variation."

Proposed revision:

"For bars from Switzerland, the 95% confidence interval on the difference just barely includes the value zero. Thus, the difference between the mean ratings of US and Swiss chocolate bars is barely not significant at the 5% level."
