Question 50 1 pts The director began the analysis by calculating the SSTR as shown in this ANOVA table: Source of Sum of Squares Degrees of Mean Square F Critical Variation Freedom value of F Treatments 260.64 Error Total Using this value for the SSTR and the information given in the study description and sample table in the previous question, calculate the Mean Square due to Treatments. What is the MSTR? Report this value to two decimal places: 86.88 D Question 51 1 ptsD Question 45 1 pts For questions 45 through the end of the exam, consider the following: A pet food manufacturer was considering adding some new kibble mixes to its line of dry dog foods. The manufacturer wanted to test the appeal of the new mixes before introducing them. The manufacturer prepared four mixes with a different predominant flavor in each: Salmon, Turkey, Chicken, and Beef. The manufacturer recruited a local animal shelter to participate in the study. 64 dogs at the shelter were divided randomly into four different groups, one group per mix. At mealtime, each dog was given a serving of food. After each dog finished eating, the amount that it ate was measured. In this study, the experimental units are: O the servings of food the animal shelter O the flavors the dogs D Question 46 1 pts What are the treatments? O flavorQuestion 49 1 pts The amount of food eaten by each dog was recorded in grams, and the mean and variance of each group of dogs was calculated. The results of the study are summarized in the following table: Group Number Sample Size Sample Mean Sample Variance Flavor (n;) (x;) (s? ) Salmon 16 27.4 18.3 N Turkey 16 27.7 18.6 3 Chicken 16 28.3 15.2 4 Beef 16 32.4 10.6 The research director decides to perform an ANOVA at the a = 0.05 level of significance. What is the overall sample size, nT? 0 64 O 16 0 4 It is not possible to tell with the given information D Question 50 1 ptsQ X 2 A Question 51 1 pts The research director asks you to calculate the Sum of Squares due to Error (SSE). What is the SSE? O 214,814.9 1201.14 O 940.5 D Question 52 1 pts What are the degrees of freedom for the Mean Square due to Error (MSE)? This is df2. O 60 0 63 O 61 0 3 D Question 53 1 pts
