# Question

The fill volume of soft-drink beverage bottles is an important quality characteristic. The colume is measured (approximately) by placing a gauge over the crown and comparing the height of the liquid in the neck of the bottle against a coded scale. On this scale a reading fo zero corresponds to the correct fill height. Fifteen samples of size n = 10 have been analyzed, and the fill heights are shown in Table 6E.6.

(a) Set up x and S control charts on this process. Does the process exhibit statistical control? If necessary construct revised control limits.

(b) Set up an R chart, and compare it with the s chart in part (a).
