(15 points) Sable systems believes that there is a strong relationship between its monthly factory maintenance costs and the number of hydrogen fuel cells produced in its manufacturing facility. Sable has collected the data, shown below, from last year's production volume and maintenance costs, and hopes to be able to use it to analyze this relationship.

(15 points) Sable systems believes that there is a strong relationship between its monthly factory maintenance costs and the number of hydrogen fuel cells produced in its manufacturing facility. Sable has collected the data, shown below, from last year's production volume and maintenance costs, and hopes to be able to use it to analyze this relationship. Required: 1. Use High-Low analysis to determine the cost function (variable cost per unit and fixed cost) that relates units produced to maintenance costs. State the function in TC = FC + VC*units form. 2. The partial results from a least squares regression performed on the dame data gave the following: R-square - 9498 Intercept - 3986 Slope - 6.70 Compare these results to you answer above and comment briefly. What does the R-square coefficient indicate regarding the strength of the retationship? 3. Make predictions using both models at a production level of 1200 units. Note any concern with making the prediction at this level of production
