I need someone to complete the tasks 4a to 4d listed in the attached file. The tasks description is addressed in the file. Several files will be uploaded later on to be used to solve the assignment and some parts of the assignment will require some parts of previous assignment that I haven’t finished yet. But will upload them as soon as I do. Contact me if you have experience on this topic. The assignment length is 10 pages including graphs and figures you can go upto 15 if needed but all points in each task need to be addressed!
