In your case that is always 10.345% independent of the exact value of e d u c a t i o n. Regression coefficient the value of regression coefficient associated with a specific independent variable in the linear model. Before we can derive confidence intervals for α and β, we first need to derive the probability distributions of a, b and σ ^ 2.
