Bars of Rex Crunch, an energy snack bar, are labelled "net: 60 g." To determine if the production process was in statistical control, a sample of 5 bars was selected from the production lot each day for 10 days. The mass of each bar (in grams), along with the sample range and mean are shown in the table below (some values are missing). a) Determine the missing values. The missing sample observation is the minimum value for each of the samples taken on Days 2, 4 and 6 while for Days 3 and 10, the missing sample observation is the maximum.
