Respond to each requirement with a separate header and code chunk in the RMD file. Data preparation: Replace the values in the following columns with the same value divided by 1,000: loan_amount, property_value, and income. (This will make it easier to see the impact on the interest rate.) Create a new column, ltp, that is equal to the values in the loan_amount column divided by the values in the property_value column. Filter the data to keep observations for which income is less than 300 (i.e., $300,000). Display a summary of all columns
