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.
