This is a coding question. Try to program a Ridge regression. Please complete the coding. Note that here the data set we use has just one explanatory variable and the Ridgc regression we try to create here has just one variable (or feature). Now that you have finished the program. What are the obscrvations and the corresponding predictions using Ridge? Now, make a plot to showoase haw well your model predicts against the observations. Use scatter plot for observations, line plot for your model predictions. Observations are in color red, and predictions are in color green. Add appropriate labels to the x axis and y axis and a title to the plot. You may also need to tine tune hyperparamoters such as learning rate and the number of iterations. side note- make sure the code runs successfully
