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. Find Median and two quartiles. 2. Find mean and Standard deviation for each source and compare them. 3. Which source do you think providing better quality of components and why? Note: answer this part by considering results of mean and standard deviation. 4. Find Quartile Deviation in terms of absolute and relative measure of dispersion.
