ISM6562 Finаl Exаm - Prоgrаmming Pоrtiоn - Spring 2023 **You have less than 90 minutes to complete and submit this exam portion. Late submissions will not be accepted.** You must choose ONE of the following: Normal Level Problem or Easy Level Problem. The most you can make for an Easy Level question is 8/10. The most you can most for a Normal level question is 10/10. You can only do one question. **NORMAL LEVEL PROBLEM (max possible mark 10/10)** In this programming portion of the exam, you will use PySpark to analyze a dataset. The dataset is provided in the file `transactions.csv.` The dataset contains transaction information for each sale at a given company. (the format of this part of the exam is 'quiz' with one question that you answer, which contains the file upload) Instructions: 1. Download the data file and starter notebook. 2. Rename the starter notebook to include your name. For example, if your name is John Smith, rename this file to "John_Smith.ipynb" 3. Complete the programming portion of the exam as outlined in the starter notebook. a. There are four sections (7 questions in total). b. Notice the time estimate provided for each section. You should use this as a guide to help you manage your time. 3. Submit your completed Jupyter Notebook file to Canvas. The notebook will be tested by running it against the original transactions.csv file. **EASY LEVEL PROBLEM (max possible mark 8/10)** You are given housing prices for a given market (WestRoxbury.csv) Create a Jupyter notebook that analyzes this data using PySpark. Load the data into a pyspark dataframe and conduct any necessary datatyping/casting. In the notebook, you must answer the following questions using code. 1) Identify the top 10 most expensive homes. 2) Create a linear regression model that predicts home prices using LOT SQFT, YR Built, Gross Area, Living Area, and REMODEL variables. (be sure to conduct a train/test split and fit the model to the training data) 3) Evaluate the performance of your model on the test data NOTE on EASY LEVEL PROBLEM: The column names have extra whitespace. You can either write code to remove these whitespaces or be extra careful when referencing the columns so that you include any leading and trailing whitespace. You can see a list of a PySpark data frame column names by printing df.columns (change df to reflect the actual name of your PySpark data frame) Good luck!
