The graph below includes the results of a linear regression using this data. (For example, the client identified with the grey square in the graph has a BMI of 29.28 and has cost the insurance company $22,411 over the previous 60 months.) Insurance Charges ($$) 70000 60000 50000 40000 30000 20000 10000 0 Males Smokers, aged 40 to 64 y = 1487x-9399.7 R² = 0.6501 18 23 28 33 38 43 BMI Another client is indicated by a large black triangle on the graph. Would the residual of the prediction for this client be positive or negative? Briefly explain how you would know without using arithmetic.
