Because of high production-changeover time and costs, a director of manufacturing must convince management that a proposed manufacturing method reduces costs beforethe new method can be implemented. The current production method operates with a mean cost of $240 per hour. A research study will measure the cost of the new methodover a sample production period.(a) Develop the null and alternative hypotheses most appropriate for this study.O Ho: H > 240Hus 240O Ho: H2 240H:µ < 240o Ho: H = 240H:u# 240O Ho: HS 240H: > 240Ho:H< 240H:u2 240(b) Comment on the conclusion when Ho cannot be rejected.O There is not enough evidence to conclude that the new method reduces costs.
