Question

Not sure how to answer this question, help is very much appreciated :)

A manufacturing company designed a Factorial Experiment to determine whether the number of defective parts produced by two machines (the "Sample" row in the ANOVA table)
differed and if the number of defective parts produced also depended on whether the raw material needed by each machine was loaded manually or by an automatic feed system (the
"Columns" row in the ANOVA table). Assuming that alpha is 0.05, and looking at the information in the "Columns" row in the ANOVA table,
#1, would you Reject or Fail to Reject the Null hypothesis that the two Loading Methods produce the same average number of defective parts? And,
#2, EXPLAIN specifically what you used in the ANOVA table to arrive at your decision.
