The manager of the main laboratory facility at Capital Health Center is interested in being able to predict the overhead costs each month for the lab. The manager believes that total overhead varies with the number of lab tests performed but that some costs remain the same each month regardless of the number of lab tests performed. The lab manager collected the following data for the first seven months of the year: (Click the icon to view the data.) Read the requirements C. Data Table Requirement 1. Prepare a scatter plot of the lab's volume (number of lab tests performed) and total laboratory overhead costs. Plot the points on the graph.
