The linear regression model of two numerical variables X and Y is given by ?? = -10X? + 47 where 10 ? X? ? 70. The intercept 47 represents Select one: a. the predicted decrease of the value of Y, if X increases one unit b. the predicted increase of the value of Y, if X increases one unit c. the predicted increase of the value of X, if Y increases one unit d. the predicted average value of X when Y is equal to zero e. the predicted average value of Y when X is equal to zero f. the predicted decrease of the value of X, if Y increases one unit

Consider the regression model: n + xg = x Where u and s satisfy the assumptions specified here. Let's denote an estimator of β that is constructed as β̂ = (Y - Ȳ) / (X - X̄), where Y and X are the sample means of Y and X respectively. Show that β̂ is a linear function of Y: β̂ = Ȳ + Y + Ȳ. Show that β̂ is conditionally unbiased: E(V(X^2) / (X^2) * xn) = B(X̄ / X).
