# Question

Consider a simplified version of equation 8.19 (below). Note that this was obtained by assuming that the term 9n in equation 8.19 will probably be large. Rework Exercise 8.24 using this equation and compare your answer to the original answer obtained from equation 8.19. How good is the approximation suggested in this problem?

An operator-instrument combination is known to test parts with an average error of zero; however, the standard deviation of measurement error is estimated to be 3. Samples from a controleld process were analyzed, and the ...The data in Table 8E.11 were taken by one operator during a gauge capability study. (a) Estimate gauge capability. b) Does the control chart analysis of these data indicate any potential problem in using the gauge? Perform a process capability analysis using x and R charts for the data in Exercise 6.7. A sample of 20 measurements on a normally distributed quality characteristic had x = 350 and s =10 .
