ET 603  Problem Set 7

 
7a.  Using the data from Problem Set 6, run the same type of DOE using Minitab

        And compare your results to your findings produced by using Excel and 

        “manual” calculations.   Discuss how the procedures differ and how the

        results compare.  (In class work in groups, write-up will be individual).

 
7b.  The following experiment was conducted on a chemical process to

       determine the effects of temperature, pressure, and reaction time on yield of

       the produced product with respect to purity.   

       Complete the appropriate DOE in Minitab and analyze the results.  Produce

       interaction plots where (and if) appropriate, and make recommendations of

       your findings.
