My Notes Ask Your Teac 9. 0.14/022 points Because of variability in the manuracturing process, the actual yielding point of a sample of mild steel subjected to increasing stress will usually differ from the theoretical yielding point. Let p dencte the true proportion of samples that yield before their theoretical yielding point. If on the basis of a sample it can be concluded that more than 20% of all specimens yield before the theoretical point, the production process wll have to be modifled. ! Prevous Answers Devoresta妼8,E.080. + (a) If 14 of 60 speclmens yleld before the theoretical polnt, what Is the p-value when the approprlate test is used? (Round your answer to four declmal places.) p-value= 0.2593 What would ynu 」advise the company to do? Because the p-value is rather large, Ho would not he rejected at any reasonable α, so the production process will have to be mad!fled ◆ Because the p-value is rather small, Ho will be rejected at any reasonable tt, so the production process will have to be modified. Because the P-value is rather large, Hu would not be rejected at any reasonable so no modification appears necessary Because the p-value is rather small, HO will be rejected at any reasonable a, sono modification appears necessary (b If the true percentage of early yields Is actually 50% so that the theoretical point is the median of the yielc distribution and a level 0.01 test is used what Is the probability that the company concludes a modification of the process is necessary?
