This is a rare opportunity to buy the M248 book on Confidence Intervals before the rewrite of the course that occurred (I believe) in the late 2010s. It is only 48 pages, however it is arguably the best book on confidence intervals that the OU has ever produced. It provides an excellent stand alone introduction to confidence intervals.
