Question
The Best Pet Food company has a business objective of expanding its product line beyond its current Beef and Salmon cat food. The company developed two new products, one based on Chicken Liver and the other based on Shrimp. The company conducted an experiment to compare the two new products with its two existing ones, as well as a generic Kidney-based product sold in a supermarket chain. For the experiment, a sample of 40 cats was selected at the Toronto Cat Rescue Volunteer Centre. A random selection of eight cats were assigned to each of the five products being tested. Each of the cats was then presented with 5 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 interval that began when the filled dish was presented. The results of this experiment are given below. Beef 4.79 4.10 4.98 4.18 4.32 Salmon 4.86 4.90 4.76 4.86 4.86 4.69 4.46 4.88 SUMMARY Groups Beef Salmon Chicken Liver < Previous Count 8 8 Chicken Liver Shrimp 4.42 4.33 4.28 4.78 4.15 4.38 4.08 4.93 4.56 8 4.31 4.12 4.15 The researcher used Excel to generate a single factor ANOVA output for the data. The results are shown below. ANOVA: Single Factor 4.18 4.27 4.23 Sum Kidney 4.72 4.70 35.62 38.27 34.15 4.90 4.20 4.85 4.77 Average 4.453 4.784 4.269 Variance 0.087507 0.022055 0.015813
