To determine whether the pipe welds in a nuclear power plant meet specifications, a random sample of welds is selected, and tests are conducted on each weld in the sample. weld strength is measured as the force required to break the weld. suppose the specifications state that mean strength of welds should exceed 100 lb/sq in; the inspection team decides to test \(h_{0}\) ; \(\mu=100 versus h_{a}\) ; \(\mu> 100. \) explain why it might be preferable to use this \(h_{a}\) rather than \(\mu < 100.\)
