Solution
the mean of the predicted value is 3.04
the mean of the std residual is 0 and sd is 0.989. this is important to be noted as it is one of the assumptions of regression. the error mean shd be 0 and sd should be 1.
the sd of predicted value is 0.513 and also form the histogram we see that the distirbution is normal. Hence all the assumptions of linear regression are satisfied.
