1. Blood pressure dataset pressure.csv contains examples of systolic pressures and other features from different persons.

2. Create polynomial regression models, to predict systolic pressure using the weight feature, for degrees vary from 1 to 14. Perform 10-fold cross validation. Calculate its square roots of the mean square errors (RMSE), and the mean RMSE. Display the mean RMSEs for the 14 different degrees. Produce a cross validation error plot using the mean RMSE with 1 to 14 different degrees
