Problem 5 (10%). The cooling system in a nuclear submarine consists of an assembly pipe through which a coolant is circulated. Specifications require that weld strength must meet or exceed 150 psi. Suppose the designers decide to test the hypothesis Ho: μ = 150 vs H₁: μ> 150. A random sample of 20 welds results in x = 153.7 and s = 11.5 psi. What conclusions can you draw about the hypostasis. Use a = 0.05. Please show your steps.
