The manager of the main laboratory facility at CenterHealth 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.) The laboratory manager performed a regression analysis to predict total laboratory overhead costs. The output generated by Excel is as follows: (Click the icon to view the completed regression analysis.) Read the requirements.

Determine the lab's cost equation (use the output from the Excel regression). (Round the amounts to two decimal places.) y= x + Requirement 2. Determine the R-squared (use the output from the Excel regression). The R-squared is What does CenterHealth's R-squared indicate? The R-squared indicates that the cost equation explains of the variability in the data. In other words, it equation to predict total costs at other volumes within the same relevant range. Requirement 3. Predict the total laboratory overhead for the month if 3,200 tests are performed. (Round your answer to the nearest cent.) The total laboratory overhead at a volume of 3,200 lab tests is CenterHealth feel confident using this cost
