A shipment of fibers is not acceptable if the mean breaking strength of the fibers is less than 50 N. A large sample of fibers from this shipment was tested, and a 98% lower confidence bound for the mean breaking strength was computed to be 50.1 N. Someone suggests using these data to test the hypotheses H0: μ ≤ 50 versus H1: μ > 50. a) Is it possible to determine from the confidence bound whether P < 0.01?="" explain.="" b)="" is="" it="" possible="" to="" determine="" from="" the="" confidence="" bound="" whether="" p="">< 0.05?="">
