Scattergraph: The correct answer is Based on an examination of the scattergraph, does there appear to be a linear relationship between the cost of radiology service and the number of tests? 2. Compute the cost formula for radiology services using the high-low method. Round the intercept to the nearest dollar and round the slope to 2 decimal places. 3. Calculate the predicted cost of radiology services for October for 3,500 tests using the formula found in Requirement 2 . For computations, carry amounts out to two decimal places. Round your final answer to the nearest dollar
