chp 11 -- new example to frame the section

[hardin47]

would love to have a new example to replace the sex discrimination case. it is a great example, but it relies on the gender binary, and the data is extremely old.

note that we'd need a two binary variable experiment without too many observations (so that we can apply a tactile in class example).

we would also need to re-do all of the graphics that were originally created in powerpoint.
