Last month your boss sent a mailing to $20,000$ of your existing customers with a special offer on a Hoosfoos credeen. The response was exciting: $1\%$ of them responded, which brought in $$200,000$ in revenue. She has now delegated to you the task of continuing the program, and has given you a budget of $$10,000,$ which will allow you to target another $20,000$ customers $($out of your customer base of $100,000).$ You don$$t want to just target them randomly, as your boss did. Make classification tree model and a k nearest neighbour model and evaluate them before deciding which one of them is preferable
