In the manufacture of a certain scientific instrument great importance is attached to the life of a critical component. This component is obtained in bulk from two sources, A and B, and in a course of inspection, the lives of 1000 of the components from each source are determined. The following frequency tables are obtained: QI. Source A Life (hours) 1000 - 1020 Source B Life (hours) 1030 - 1040 No. of components No. of components 40 339 1020 - 1040 96 1040 – 1050 136 364 372 1040 - 1060 1050 - 1060 25 1060 - 1080 1080 - 1100 1100 - 1120 1060 - 1070 1070 - 1080 20 85 130 43 1080 – 1090 350 Examine the effectiveness of the measures of dispersion with which you are familiar for comparing the dispersion of the two distributions.
