Question
A producer of coffee, bags coffee beans with a net weight of 4 oz. The machine that fills the bags with coffee is new and the operations manager wants to ensure that it is properly adjusted. Taking, n = 8 sample bags off the line and recording the average and the range produces the following information (measured in oz): i. Calculate the control limits for this process (mean and range charts) ii. Graph the sample data for both the X-bar and R-bar charts. iii. Explain if this machine is adjusted and in control? iv. Estimate the standard deviation of the process, ô SAMPLE A B C D E F G H Sample Sample Range Average 0.41 4.00 0.55 4.16 0.44 3.99 0.48 4.00 0.56 4.17 0.62 3.93 0.54 3.98 0.44 4.01 Table 1
