Residual standard error: 0.1993 on 109 degrees of freedom
Multiple R-squared: 0.07516, Adjusted R-squared: 0.0497
F-statistic: 2.953 on 3 and 109 DF, p-value: 0.03583
The p-value = 0.03583 is the result, this means that null hypothesis is rejected, so we conclude that our model is better than a model with only the intercept because none of the coefficients β is significantly different from 0.
Furthermore, none of the predictors is considered as significant predictors for GWA.
It is shown above that the assumptions are met.
