A cоnsumer reseаrch firm cоnducts а study tо compаre the cleaning power of 3 different laundry detergents and 4 different water temperatures. Results are shown in the table below, with a higher number representing greater cleaning power. Perform a two-factor ANOVA and answer the following questions.What water temperature has the highest average cleaning power? [highwater] (enter the temp name, e.g. cool)What water temperature has the lowest average cleaning power? [lowwater] (enter the temp name, e.g. cool)What is the p-value in the ANOVA for the difference in the average water temperatures? [pvalwater] (round to 3 decimals)At an alpha of 0.05, is there a significant difference in the average water temperatures? [sigtemp] (enter yes or no)What is the p-value for the difference in the average cleaning power of the detergents? [pvaldet] (round to 3 decimals)At an alpha of 0.05, is there a significant difference in average cleaning power of the different detergents?
