In simple works, if P value for the F-Stat (here Prob (F-Statistic) is less than your significance level, one can reject the null hypothesis that a intercept-only model is better, meaning your model is better a better job (Not a big surprise honestly).

In this case MS regression / MS residual =273.2665 / 53.68151 = 5.090515. Since the p-value is less than the significance level, we can conclude that our regression model fits the data better than the intercept …
Webb'P> t '. Typically, a t-statistic above 2 or below -2 is considered significant at the 95% level. We use 2 as a rule of thumb because in the t-distribution we need to know how many degrees of freedom we have (d.f. = number of observations - number of variables) before we can decide whether the value of the t-statistic is significant at the 95%
