Please help with the blue boxes in the third image. The first two are for context. Also, assistance with excel formulas would be greatly appreciated. Thanks!

Step Instructions 1 1. Run a regression analysis using data for August through February. Determine the lab's cost equation (use the output from the regression analysis you performed using Excel). (Always use cell references and formulas where appropriate to receive full credit. If you copy/paste from the Instruction tab you will be marked wrong.) a. Rename the regression output tab name "REGRESSION". 2 2. Determine the R-square using the Excel output you obtain. (Always use cell references and formulas where appropriate to receive full credit. If you copy/paste from the Instruction tab you will be marked wrong.) 3 3. Predict the lab's total overhead costs for the month if 3,500 tests are performed. (Always use cell references and formulas where appropriate to receive full credit. If you copy/paste from the Instruction tab you will be marked wrong.) a. Reference values calculated in previous requirements as needed. Cost Behavior Performing a regression analysis to predict overhead for a hospital laboratory The manager of the main laboratory facility at Elmhurst 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 manager of the main laboratory facility at Elmhurst Health Center collected the following seven months of data. The number of tests performed and the total monthly overhead costs for the lab follow: Month August September October November December January February Number of Lab Tests Performed 3,350 3,700 3,650 3,450 4,200 2,500 3,800 Total Laboratory Overhead Costs $ 23,500 $ 27,550 $ 24,500 $ 26,400 $ 28,500 $ 22,800 $ 25,350 Use the blue shaded areas on the ENTERANSWERS tab for inputs.
