George Caloz & Frères, located in Grenchen, Switzerland, makes luxury custom watches in small lots. One of the company's products, a platinum diving watch, goes through an etching process. The company has recorded etching costs as follows over the last six weeks: Week 1 2 3 4 5 6 Units 11 15 12. 10 13 14 75 Total Etching Cost $ 22 29 24 20 24 26 $ 145 For planning purposes, management wants to know the variable etching cost per unit and the total fixed etching cost per week. Exercise 5A-5 Part 2 and 3 (Algo) Required: 2-a. Using the least-squares regression method, estimate the variable etching cost per unit and the total fixed etching cost per week. 2-b. Express these estimates in the form Y = a + bX. 3. If the company processes thirteen units next week, what would be the expected total etching cost? halou
