O |ezto.mheducationcom/hm.tpx Wenton Powersports produces dune buggies They have three assembly ines, Razor Bazer nd Tracer," named after the particular dune buggy models produped on those lines. Each assembly line was originaly designed using the same target production rate. However, over the years, various changes have been made to the Ines. Accordingly, management wishes to determine whether the assembly ines are st operting at the same average hourty prockuction rate. Production data (n dune buggles/hour) for the last eight hours are as folows 10 10 10 10 10 13 .97500 = 1.0714 T-a6250 =0.8303 n.10. 1250 2A107 1.0000 08303 a Construct an ANOVA table.
