Question

The weights of nominal 1-kg containers of a concen- trated chemical ingredient are shown in Table 8E.2. Prepare a normal probability plot of the data and esti- mate process cápability. Does this conclusion depend on process stability? Consider the package weight data in Exercise 8.13. Suppose there is a lower specification at 0.985 kg. Calculate an appropriate process capability ratio for this material. What percentage of the packages 8.13. 8.14. ■ TABLE 8E.2 Weights of Containers 0.9475 0.9775 0.9965 1.0075 101so 0.9705 0.9860 09975 1.0100 1.0200 0.0 0 0.9960' 1.KMkSO 11.0175 , 1.0250
