Find books tested to estimate to break the binding

Reference no: EM13116125

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 to estimate with 95% to within 0.1 lb, the average force required to break the binding? Assume that sd is known to be 0.8 lb.
