An analyst measured the length of 30 peanuts for classification purposes. He obtained the following measurements: 997 1002 998 1000 999 999 999 1000 1001 998 1003 1000 999 1000 1001 1000 1002 997 1002 997 1000 1001 1001 1003 998 10 01 998 1000 999 1001 Prepare a check sheet and a Pareto diagram of the diameters of peanut. What conclusions can you draw?
