Six samples of five observations each have been taken of 80 kg concrete slabs produced by a machine, and the results are displayed below. Sample 3 5 6 78.0 80.2 79.4 78.7 79.2 78.4 79.0 81. 2 78. 6 79.5 81. 8 79. 7 80 . 0 79. 8 79.0 80.4 80. 6 78.3 78.8 80. 7 81.7 79.5 79.4 81.2 80. 80.4 79. 1 79. 8 78. 7 81.0 a-1. Using factors from Table 10 3, determine the upper and lower control limits for sample mean and range. (Do not leave any empty spaces; input a 0 wherever it is required. Round your intermediate calculations and final answers to 2 decimal places.) ECL Mean control limits 8.62 0.0 78.04 0. Range control limits 6.50 0.C 0 0.01 a-2. Decide if the process is in control. O Process is in control Process is not in control b. A new sample results in the following slab weights: 80.2, 80.4, 80.0, 79.2, and 81.2. Use the control limits determined in part a to decide if the process is still in control. Process is in control. Process is not in control
