A machine produces rubber tubing of a set length: as the conveyor moves the tube, a blade cuts it at regular intervals. The customer specification for the tube length is 1026 mm, +/- 10 mm. However, there is an inconsistency in the cut length of the rubber tubes produced, so data is sampled measuring the conveyor speed and cut length. The results are showed in the table below Number Cut Length Number (mm) Conveyor Speed (cm/sec) Cut Length (mm) Conveyor Speed (cm'sec) 8.1 7.9 7.4 7.5 7.4 8 72 8 79 7.6 1 2 3 4 5 61 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 23 1046 1030 1039 1021 1028 1025 1035 1015 w 1038 1036 1026 104 1041 1029 1010 1020 1024 1034 1036 1023 1011 1030 101 TUS 1030 1016 1020 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 7.5 72 73 7.4 8 8 7.4 7.1 7.9 73 7.8 7.2 73 S 5.5 6.9 7 7.5 6.7 18.1 9 7.1 7.6 8.5 7.5 8 5.2 6.5 Te 8 169 176 65 5.5 6 5.5 7.6 8.61 163 1040 1013 1025 1020 1022 1020 1035 1052 1021 1024 1029 1015 1030 1010 1025 1031 10130 1034 1034 12 1020 1025 1022 1028 10122 1020 1026 50 1.
