A manager has taken 20 samples of the weight of a bottle being filled automatically by a machine. Each sample was n=3. The standard deviation was 20 grams (i.e., o = 20). The average weight was 200 grams (i.e., = 200). The manager wants to use z-3. For Xbar chart, what is the UCL ? UCL=X+2 The answer format should be XXX.XX Question A manager improved the bottling process. A new sample of 20 samples of the weight of a bottle being filled automatically by a machine was taken. Each sample was n=3. The standard deviation was 2 grams (i.e., o = 2). The average weight was 200 grams (i.e., = 200). The customer specifications are that the weight be greater than 198 g. What is the probability that the weight of a bottle would be less than 198g? Prob (X198) Use the Norm. Dist function in Excel, with cumulative set to true The answer format should be XX.XX A manager has taken 20 samples of the weight of a bottle being filled automatically by a machine.
