breaking strength

A producer of steel cables wants to test if the steel cables it produces have a breaking strength of 5000 lb.

A breaking strength of less than 5000 lb would not be adequate, and to produce steel cables with breaking strengths of more than 5000 lb would unnecessarily increase production costs. The producer takes a random sample of 64 pieces and finds that the average breaking strength is 5100 lb and the sample standard deviation is 480 lb. Should the producer accept the hypothesis that its steel cable has a breaking strength of 5000 lb at the 5% level of significance?
