Current Attempt in Progress Jennifer 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. Month # of Units Produced Overhead Cost 1 290 $3,230 2 250 2420 3 320 2,930 - 380 3,670 5 400 3,320 6 360 3,550 7 310 2,930 8 330 3,720 (al1) our answer is correct. Jennifer is planning to use the high-low method to estimate this cost function. Is it important for the data to exhibit a linear relationship when using this method? It| is ~| important for the data to exhibit a linear relationship. eTextbook and Media Attempts: 1 of 2 used our answer is incorrect. Help Jennifer estimate her company's overhead costs using the high-low method. Write your final model in Y = m(X} + b format. Y=% 847 | X+5 252
