You can put this solution on YOUR website! Specify the null hypothesis and alternative hypothesis in each of the following cases,
(i) An automobile manufacturer wants to confirm a suppliers claim that the maximum resistance in a wiring harness is less than 50 ohms,
HO: u <= 50 ohms (claim)
Ha: u < 50 ohms
----------------------
(ii) An investigator wants to establish the research department's claim that a new filament will increase mean bulb life of more than 3,000 hours.
Ho: u <= 3000
Ha: u > 3000 (claim)
