16. A process engineer at Sival Electronics was trying todetermine whether three suppliers would be equally capable ofsupplying the mounting boards for the new “gold plated” componentsthat she was testing. The Ch05Data.xlsx file for Prob05-16 on theStudent Companion Site shows the coded defect levels for thesuppliers, according to the finishes that were tested. Lower defectlevels are preferable to larger levels. Using one-way ANOVA,analyze these results. What conclusion can be reached, based onthese data?
