The goal of this competition is to use the tools you've learned in Sessions 2-4 to predict the prices of the remaining diamonds (i.e., those with IDs 6001 and above).

When done, create a spreadsheet containing two columns: ID and Price. For IDs, put 6001, 6002, etc., and for the prices, put the numerical values of your predictions (without dollar signs, or any other strings), e.g., 12345.6, 23456.7, etc.

Save the resultant file in the CSV format and submit it. Make sure the column names follow the uppercase and lowercase format and are exactly ID and Price. See the example in the Description section. 

Your submission will be immediately scored on a fraction of the diamonds according to the Mean Absolute Percentage Error (MAPE) metric that we will discuss in class. The lower, the better.
