(4 pts, 2 pts each) The following are the means and standard deviations of some well-known standardized tests, referred to as Test A, Test B, and Test C. All three yield normal distributions. Test Mean Standard Deviation Test A 500 100 Test B 150 8 Test C 70 15 a. (2 pts) A score of 450 on Test A corresponds to what score on Test B? b. (2 pts) A score of 625 on Test A corresponds to what score...
3) If a process has a Cpk of 1.33, How many Standard Deviations would that cover? If the process produced 100,000 parts, how many non-conforming parts would you expect to produce? Would you feel the need to 100% Inspect?
