Exercise 5A-5 (Algo) Least-Squares Regression [LO5-11]

Skip to question

George Caloz & Frres, located in Grenchen, Switzerland, makes luxury custom watches in small lots. One of the companys products, a platinum diving watch, goes through an etching process. The company has recorded etching costs as follows over the last six weeks:

Week	Units	Total Etching Cost
1	13	$ 24
2	11	21
3	16	31
4	15	25
5	18	31
6	18	32
	91	$ 164

For planning purposes, management would like to know the variable etching cost per unit and the total fixed etching cost per week.
