1.The output of a process is considered acceptable if it weighs between 99 and 101 grams. The process which produces this product delivers an average weight of 100 grams with a standard deviation of 1 grams. The fraction of products that are out of specs is about:a.70%b. 15%c. 30%d. 5%2. Suppose the production of a product has 10 sequential steps each of which has a yield of 95%. Then the yield of the process:a. Is lower than 95%.b. Is 95%.c. Is higher than 95%.d. May vary.3.A sample average which is outside of the control limitsa. Should lead to the investigation of the process.b. Is impossible to be observed.c. Indicates that the products in the sample are all defective.d. Indicates that no process variation is present.
