The following are the numbers of defective solder joints found during successive samples of 100 solder joints: Day No. of Defectives Day No. of Defectives 1 44 11 36 2 46 12 62 3 32 13 35 4 40 14 41 5 29 15 42 6 31 16 30 7 46 17 46 8 64 18 38 9 44 19 18 10 46 20 30 4 a. Using all the data, compute trial control limits for a fraction-defective control chart. (13 points) b. Determine whether the process is in statistical control. If the process is out of control, you do not need to construct revised control limits. (6 points)
