I've got a regression from the value of a house on things like
x1 = number of bathrooms,
x2 = number of bedrooms,
x3 = age of the house and a couple more. I have the estimates of the coefficients belonging to those variables as well as their standard error, t-value, p-value and 95% CI.
Moreover, I got the number of observations, $R^2$, adjusted $R^2$ and the standard error of $y$.
Now I am supposed to calculate the average value of a house, which is the average value of $y$. But I got no idea how to calculate it with the information I have. Can anyone give me a hint?
