A pet food company conducted an experiment to compare five different cat foods. A sample of 30 cats from the population at a local animal shelter was selected Six cats were randomly assigned to each of the five products. Each was then presented with 3 ounces of the selected food in a dish at feeding time. The researchers defined the variable to be measured as the number of ounces of food that the cat consumed within a 10-minute time interval. The results for this experiment are summarized in the accompanying table Complete (a) through (d) below. Click on the icon to view the results. Run STATCRUNCH or SPSS to get the required information! You may need to run the Tukey procedure! a. At the 0.05 level of significance, is there evidence of a difference in the mean amount of food eaten among the various products? Determine the hypotheses. Choose the correct answer below OA H₂H₁₂ H, Not all , are equal (where j-1.2.-6) OC. H₂H₁₂ H₂: Hy *₂#****HS Find the test statistic Fate (Round to two decimal places as needed.) Determine the critical value F(Round to two decimal places as needed.) Reach a decision. Ho. There is OB. HP₂ H.: Not all, are equal (where - 1,25) OD. H H evidence of a difference in the mean amount of food eaten among the various products.

b. If appropriate, determine which products differ in the mean amount of food eaten. Let the kidney-based cat food be group 1, the shrimp-based cat food be group 2, the chicken liver-based cat food be group 3, the salmon-based cat food be group 4, and the beef-based cat food be group 5 Is there significant evidence that group 1 and group 2 differ in the mean amount of food eaten? A. Yes OB. No OC. It is not appropriate to test which products differ in the mean amount of food eaten. Is there significant evidence that group 1 and group 3 differ in the mean amount of food eaten? A. Yes OB. No OC. It is not appropriate to test which products differ in the mean amount of food eaten. is there significant evidence that group 1 and group 4 differ in the mean amount of food eaten? OA. Yes OB. No OC. It is not appropriate to test which products differ in the mean amount of food eaten

Is there significant evidence that group 3 and group 5 differ in the mean amount of food eaten? OA. Yes B. No OC. It is not appropriate to test which products differ in the mean amount of food eaten. Is there significant evidence that group 4 and group 5 differ in the mean amount of food eaten? OA. Yes B. No OC. It is not appropriate to test which products differ in the mean amount of food eaten. c. At the 0.05 level of significance, is there evidence of a difference in the variation in the amount of food eaten among the various products? Determine the hypotheses. Choose the correct answer below. OB OA H₂0²0- .-0² H₁: Not alle are equal (where j=1,2,....5) ⒸC H₂00 H₁:0² *0²# ₂00 =0 H₁: Not all o are equal (where j=1.2.6) OD H H0²020²

Reach a decision. Ho. There is evidence to conclude that there is a difference in the variation in the amount of food eaten among the various products. d. The pet food company has a business objective of expanding its product line beyond it current kidney- and shrimp-based cat foods. The company developed two new products, which are the chicken liver and salmon-based cat foods. The beef-based cat food is a generic product sold in a supermarket chain. What should the company conclude in terms of expanding its productine? Choose the correct conclusion below. OA. The chicken liver-based cat food is the best choice for expansion. The salmon-based cat-food is a possibility for expansion; its mean amount of food eaten is significantly larger than the beef-based cat food, but smaller than the other cat foods. OB. The salmon-based cat food is the best choice for expansion. The chicken liver-based cat-food is a possibility for expansiont; its mean amount of food eaten is significantly larger than the beef-based cat food, but smaller than the other cat foods OC. It does not matter which product(s) is/are used for expansion because there are no significant differences in the mean amounts eaten among the various products.
