There are four different machines to produce one of the products. You claim that that the weights of the products in the different machine is different. The machines need justification.
You randomly select five products from each machine from trials on an automated driving
machine. At the 0.05 significance level, is there a difference among machines in the mean
weight of the product? Test this claim showing all calculation steps clearly in the Ms. World
file (25P) and draw an ANOVA Table for the solution (10P).
