For regression problems, our baseline is the "blind" prediction that is just the average value of

the target variable. The blind prediction must be calculated using the training data. Calculate

and print the test set root mean squared error $($test RMSE$)$ using this blind prediction. I have

provided a function you can use for RMSE.
