Question

A regular type of laminate is currently being used by a manufacturer of circuit boards. A special laminate has been developed to reduce wavpage. The regular laminate will be used on one sample of specimens the specie laminate an another sample, f the amount of wavpage will then be for each specimen. The manufacturer will then to the special laminate only if it can be demonstrated that the time average amount of wavpage for laminate is less than for the regular laminate. State the relevant hypotheses. a) H_o: u_regular = u_special H_alpha: u_regular > u_special b) H_o: u_regular = u_special H_alpha: u_regular

Explanation / Answer

As our aim is to know whether the true average amount for special is less than for the regular, so Part a with alternative hypothesis having “regular>special” sign is appropriate because this means special is less than regular
