Webster Chemical Company produces mastics and caulking for the construction industry. Theproduct is blended in large mixers and then pumped into tubes and capped.Webster is concerned whether the filling process for tubes of caulking is in statistical control. Theprocess should be centered on 8 ounces per tube. Several samples of eight tubes are taken andeach tube is weighed in ounces. Assuming that taking only 6 samples is sufficient, is the processin statistical control?
