Model significance for the solar-twins sample: assumed regressions and F-value.
| H0 | [Eu/Mg] = 0.0168 × age + 0.1328 |
|---|---|
| H1 | [Eu/Mg] = 0.0076 × age + 0.1181 for age ≤ 4 Gy[Eu/Mg] = 0.0175 × age + 0.1367 for age > 4 Gy |
| F-value | 0.4643 |
| F-critical | 3.119 |
Notes. The critical F-value is given for a right-tailed test, with a false-rejection probability α = 0.05, and the two degrees of freedom are 2 and 75.
