This example uses time-to-failure data from a life test done on incandescent light bulbs. The observed times-to-failure are given in the next table.
| Order Number | Hours-to-failure |
|---|---|
| 1 | 361 |
| 2 | 680 |
| 3 | 721 |
| 4 | 905 |
| 5 | 1010 |
| 6 | 1090 |
| 7 | 1157 |
| 8 | 1330 |
| 9 | 1400 |
| 10 | 1695 |
Do the following:
- Plot the data on a Weibull probability plot and obtain the Weibull model parameters.
- Compute the B10 life of the bulbs.
