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