Model Form #1
DS =
- 13.701 + 0.642 SC
where:
- DS is computed diss. solids, in milligrams per liter
- SC is specific conductance at 25 degrees Celsius, in microsiemens per centimeter

| Intercept | -13.701 | 12.489 | SC | 0.642 | 0.0129 |
Correlation Matrix
A correlation matrix is not available for this model. Therefore, the prediction interval was calculated by assuming that there is no correlation between the explanatory variables.
