The manager of the main laboratory facility at MetroFit Center is interested in being able to predict the overhead costs each month for The laboratory manager performed a regression analysis to the lab. The manager believes that total overhead varies with the predict total laboratory overhead costs. The output generated number of lab tests performed but that some costs remain the sam by Excel is as follows: 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.) Requirement 1. Determine the lab's cost equation (use the output from the Excel regression). (Round the amounts to two decimal places.) y=x+ Data table Data table Requirements 1. Determine the lab's cost equation (use the output from the Excel regression). 2. Determine the R-squared (use the output from the Excel regression). 3. Predict the total laboratory overhead for the month if 2,900 tests are performed
