The manager of the main laboratory facility at UrbanFit Center is interested in being able to The laboratory manager performed a regression analysis to predict total laboratory predict the overhead costs each month for the lab. The manager believes that total overhead overhead costs. The output generated by Excel is as follows: varies with the number of lab tests performed but that some costs remain the same each month (Click the icon to view the completed regression analysis.) regardless of the number of lab tests performed. The lab manager collected the following data for the first seven months of the year. Read the requirements. (Click the icon to view the data.) 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 2,600 tests are performed
