<s>[INST] Stainless steel vats are used in chemical plant to store strong chemicals. They are subjected to the stresses of heat, chemical reactions and corrosion. A study was carried out to look at the effect of corrosion on stainless steel vats. A sample of 19 vats was tested to determine the relationship between the surface area of the vat and the time it takes for the vat to corrode. The following data were recorded:

| Surface Area (cm2) | Time to Corrode (years) |
| --- | --- |
| 48.6 | 82.5 |
| 23.5 | 65.4 |
| 37.1 | 89.8 |
| 17.5 | 62.3 |
| 44.6 | 87.5 |
| 37.3 | 68.1 |
| 26.7 | 65.5 |
| 17.6 | 59.8 |
| 43.8 | 79.8 |
| 38.4 | 81.3 |
| 28.1 | 67.8 |
| 18.5 | 56.2 |
| 33.6 | 75.2 |
| 25.6 | 83.1 |
| 21.2 | 70.4 |
| 35.8 | 74.3 |
| 42.9 | 79.1 |
| 19.4 | 61.8 |
| 32.7 | 66.4 |
| 40.1 | 78.3 |

The objective of this study was to investigate the relationship between surface area and time to corrode for stainless steel vats. Which of the following are the necessary steps in order to apply simple linear regression analysis to the given data?[/INST]
