Chapter 8, Problem 8.54(choose chapter or problem)
basis of a sample it can be concluded that more than 20% of all specimens yield before the theoretical point, the production process will have to be modified. a. If 15 of 60 specimens yield before the theoretical point, what is the P-value when the appropriate test is used, and what would you advise the company to do? b. If the true percentage of early yields is actually 50% (so that the theoretical point is the median of the yield distribution) and a level .01 test is used, what is the probability that the company concludes a modification of the process is necessary?
