Your company must maintain about 8,000 pumps that keep breaking down. The engineers claim that adding an extra brace to the devices will significantly increase the time between repairs. It requires a couple hours and $50 in parts to install each brace. State the null and alternative hypothesis in context and symbolically. Explain in context what the consequence of a type one error in this test. Explain in context what the consequence of a type two error in this test.
