Chapter 19 Split-Plot Designs - Purdue University
Chapter 19 Split-Plot Designs Split-plot designs are needed when the levels of some treatment factors are more difficult to change during the experiment than those of others. The designs have a nested blocking structure: split plots are nested within whole plots, which may be nested within blocks. Example . An experiment is to compare the yield ...

A random sample of 26 offshore oil workers took part in a simulated escape exercise, and their times (sec) to complete the escape are recorded. The sample mean is 370.69 sec and the sample standard deviation is 24.36 sec. Construct a 95% lower confidence bound on the true average escape time.
