The phrase "a statistically significant coefficient" is correct and usable in written English.
It is typically used in the context of statistical analysis to indicate that a coefficient in a regression model is unlikely to have occurred by chance, suggesting a meaningful relationship between variables.
Example: "The analysis revealed a statistically significant coefficient for the variable, indicating a strong correlation with the outcome."
Alternatives: "a meaningful coefficient" or "a significant statistical coefficient".
A statistically significant coefficient of the selection term indicates sample selection bias.
Now, consider the effect on African-Americans who are high school graduates, for whom we find a statistically significant coefficient of −0.202 for the Mexican concentration variable.

The results for log annual wages are presented in the second column of Table 6; Stayer has a statistically significant coefficient of 0.024, suggesting that recent graduates who stay in the large metropolitan area where they completed their degree actually earn slightly higher annual wages than recent graduates from large metros who leave.
Contrary to Model 3 a statistically significant coefficient of the interaction term was found in Model 4, which demonstrates that inclusion of WC information in addition to BMI status improves the prediction of obesity related health costs.
However, in Model 5 (which is equivalent to Model 3 but only includes the subgroup of individuals with BMI<30 kg/m2 and WC <88 cm for women and <102 cm for men), the interaction term is associated with a statistically significant coefficient (p<0.01) for women.
A negative and statistically significant coefficient would indicate that counties with higher poverty rates had a decrease in labor force participation (or other dependent variables) after the Medicaid expansions, as more people quit their jobs to qualify for expanded Medicaid.
