Q#1 In the manufacturing of a certain scientific instrument great importance is attached to the life of a particular critical component. This component is obtained in bulk from two sources, A and B, and in the course of inspection, the lives of 1000 of the components from each source are determined. The following frequency tables are obtained: Source A Source B Life (hours) No. of components Life(hours) No .of components 1000-1020 40 1030-1040 339 1020-1040 96 1040-1050 136 1040-1060 364 1050-1060 25 1060-1080 372 1060-1070 20 1080-1100 85 1070-1080 130 1100-1120 43 1080-1090 350 1.
