Exercise:

Exercise objective: Utilize what you have learned to conduct an analysis of a one way ANOVA using MINITABTM.

• The quality manager was challenged by the plant director as to why the VOC levels in the product varied so much.  The quality manager now wants to find if the product quality is different because of how the shifts work with the product. 

• The quality manager wants to know if the average is different for the ppm VOC of the product among the production shifts.

•  Use Data in columns “ppm VOC” and “Shift” in “hypotest stud.mtw” to determine the answer for the quality manager at a 95% confidence level.
