Confidence
intervals can easily be put around the difference between two means

This page shows how to construct

around (m_{i}  m_{j}) for the oneway ANOVA by continuing an example shown on a previous page. Later on the topic of estimating more general linear combinations of means (primarily contrasts) will be discussed, including how to put confidence bounds around contrasts.
