Required: Using the Mrierosoft Excel, aeate an "X-Y Scatterplot" chart. develop a cost function (inear cost equation) for ase in estimating neonthly electricity costs. What is the linear equation displayed by Excel? B. Evplain what the " R-Squared" (R2) value (Co-efficient of Determination) that Ercel displays meane. How do you interput this vahue? C. Using the cost armation you developed in "B" above, extinste the total electricity costs for a month in which 3,000 nachine hogrs are worked.
