A lead inspector at Electro Tech, an electronics assembly shop, wants to convince management that it takes longer, on a per-component basis, to inspect large devices with many components than it does to inspect small devices because it is difficult to keep track of which components have already been inspected. To prove her point, she has collected data from the last 25 devices. The data are shown in the accompanying table. Number of Components on Device 3213971514272980201969254613211223 89885558289585 Time (sec) 123 100- Inspection Time (seconds) 0- 0 84 49 30 60 51 41 71 22 42 63 26 80 48 31 62 60 72 a.
