A manufacturer has three machine lines (Red, White, and Blue) that produce the same product.The product can be scrutinized for eccentricity based on an evaluation process that returns a raw score indicating the product's departure from the standard (a higher score indicates more eccentricity).Six products are chosen at random from each line.
Conduct a Kruskal-Wallis test to see if the production lines appear to differ.Use a approximation.Select the appropriate critical value (CV), test statistic (TS), and decision.(Use α = 0.05.)
A) CV = 6.47, TS = 5.9915, fail to reject H₀
B) CV = 27.5871, TS = 10.56, fail to reject H₀
C) CV = 7.8147, TS = 3.22, reject H₀
D) CV = 5.9915, TS = 6.47, reject H₀
