I have been asked to calculate the sample size to compare the failure of two
adhesives. I need to show that the failure of the new adhesive, as measured
by the number of failed bonds in a given time period, is no worse than the
existing adhesive. My experience of sample size calculations is limited to
simple anova experiments, amd my textbooks and web searches have yielded no
useful information. Can anybody suggest a reference or technique that I can
use to get started.
Thank tou.
Janet
