A manufacturer of college textbooks is interested in estimating the strength of the bindings produced by a particular binding machine.  Strength can be measured by recording the force required to pull the pages from the binding.  If this force is measured in pounds, how many books should be tested in order to estimate with 95% confidence to within 0.1 lb the average force required to break the binding?  Assume that is known to be .8 lb.
