The F-statistic is a test on ratio of the sum of squares regression and the sum of squares error (divided by their degrees of freedom). If this ratio is large, then the regression dominates and the model fits well. If it is small, the regression model is poorly fitting.
Errors are normally distributed with mean 0 .
The point lies 1 unit below the regression line.
the prefix of regression is regress
There is no direct link. Galton, who developed the theory of regression, found that tall parents tended to have taller children but that the children's height regressed towards the mean. In short, there is no way of telling.There is no direct link.

(mean x, mean y) is always on the regression line.

8.7.4 Properties of Regression Coefficients:(a) Correlation coefficient is the geometric mean between the regression coefficients. (b) If one of the regression coefficients is greater than unity, the other must be less than unity.(c) Arithmetic mean of the regression coefficients is greater than the correlation coefficient r, providedr > 0.(d) Regression coefficients are independent of the changes of origin but not of scale.

As Dalton's study on regression showed, parents' heights are not sufficient to predict their children's heights. In fact, the word "regression" comes from his findings that tall parents had tall children BUT that the children's heights also regressed towards the population mean.
