Margaret was attempting to estimate a model for her small business's overhead costs. She is 99.9% sure that overhead costs are driven primarily by production but she also knows that this cost isn't entirely variable. So she grabbed the last 8 months of production and overhead cost data listed it out, and plotted it as follows. Margaret is planning to use the high-low method to estimate this cost function is it important for the data to eshibit a linear relationahip when using this method? important for the data to eathbit a linear retationsip. eTextbook and Media Attempts: 0 of 2 used (b) Help Margaret estimate her companys overhead costs using the hightow method. Write your final model in Y=m00+6 format. Y=5 x+5
