Production managers on an assembly line must monitor the output to be sure that the level of defective products remains small. They periodically inspect a random sample of the items produced. If they find a significant increase in the proportion of items that must be? rejected, they will halt the assembly process until the problem can be identified and repaired. Complete parts a through d below.?a) In this? context, what is meant by the power of the test the inspectors? conduct? A. The power is the probability that the assembly process continues because the proportion of items that must be rejected has not increased. B. The power is the probability that the assembly process is stopped when a high number of defective items are being produced. C. The power is the probability that the assembly process is stopped when it should not be because the proportion of items that must be rejected has not increased. D. The power is the probability that the assembly process is not stopped when it should be because a high number of defective items are being produced. ?b) They are currently testing8items each hour. Someone has proposed they test13items each hour instead. What are the advantages and disadvantages of such a? change?The advantage is that it ? increases decreases the ? probability of a Type I error. cost and time needed. power of the test. The disadvantage is thatincreasingthe number of items tested will ? increase the probability of a Type I error. decrease the power of the test. cost more money and take more time. increase the power of the test. ?c) Their test currently uses a1?%level of significance. What are the advantages and disadvantages of changing to a significance level of2?%?The advantage is that it ? decreases increases the ? power of the test. probability of a Type I error. cost and time needed. The disadvantage is that it ? increases the probability of a Type I error. costs more money and takes more time. decreases the power of the test. increases the power of the test. ?d) Suppose that as a day passes one of the machines on the assembly line produces more and more items that are defective. How will this affect the power of the? test?The power of the test will ? increase decrease because as the problem gets ? larger, smaller, it becomes ? harder easier to detect.
