An engineer of aircraft windshields wants to investigate how well the windshields can withstand projectile impacts at a range of velocities. The engineer subjects a random sample of windshields to projectiles at one of eight velocities and records whether the windshields withstood the impact.
You can use this data to demonstrate Probit Analysis.
| Worksheet column | Description |
|---|---|
| Stress | The velocity measurement of the projectile |
| N | The number of windshields that were tested at a particular velocity |
| Breaks | The number of windshields that failed under the velocity stress |
