Let’s indicate the number of nonflavanoid phenols based on the number of flavanoids, total phenols and evaluate our model.

Your plan:

[Line #24] Split the data 70-30 (70% of the data is for training and 30% is for testing) and insert 1 as a random parameter.
[Line #25-26] Initialize and fit the model (assign the model to the variable model2).
[Line #30-31] Calculate the MAE and assign the result to the variable MAE.
[Line #34-35] Calculate the R-squared and assign the result to the variable r_squared.
[Line #38] Print the intercept, the MAE and the R-squared in this order and round each value to second digit.
