A craft brewing company packages batches of its custom beer by using automatic fill machines fitted with sensors to dispense into foil-sealed single-serve beer mugs. The production operator is tasked with taking a sample each hour, where every sample must consist of 4 sealed mugs. The operator measures the volume of beer in each mug and records the 4 values in a spreadsheet. Then she calculates the average beer volume and the range of volumes for each sample. The table below shows the average volumes and range of volumes for samples she tested across her 10-hour shift. Sample Average beer volume in 4 sampled beer bottles /ml Range of volume in 4 sampled beer bottles /ml 1 265 2 2 277 2 3 274 8 275 7 282 3 274 4 273 10 270 5 276 14 10 264 5 a) Showing your calculations clearly, construct the appropriate control chart for determining if the process is in control for the data provided. (10 marks) b) What type of data does the control chart analyse? (1 mark) c) Determine whether the process is in control. (1 mark) d) If there are any out of control points, outline 2 possible cause types that could have caused them. Giving a specific example of each type, outline how you could address your specific cause in order to be able to return the process to a state of control.
