The manager of the main laboratory facility at Rosedale 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. After running a regression analysis on the first seven months of the year, the manager of the main laboratory facility at Rosedale Health Center collects seven additional months of data. The number of tests performed and the total monthly overhead costs for the lab follow: D. Click the icon to view the data.) Read the requirements. Requirements 1 and 2.
