You are interested in expanding your research to determine if type of Honda or the colour affects sales. The data below represents the annual sales in hundreds of thousands: Red Blue Green Yellow Black Small 54 49 96 51 76 Medium 44 50 50 55 80 Large 35 64 89 48 61 The study is replicated for Toyota motor vehicles and the results shown below: Red Blue Green Yellow Black Small 40 64 49 45 68 Medium 45 55 45 50 84 Large 50 49 64 64 26 Combine the data from the two and e. Prepare the analysis of variance table manually (Show ALL workings) f. State the null hypothesis(es), the decision rule for α = 0.05 and make the decision for each hypothesis. g. Confirm your answer using R-Studio. Provide the code used and relevant output tables. h. Using R-Studio, carry out relevant tests to determine if the assumptions of normality and homogeneity of variance were violated. Carefully discuss your findings quoting relevant statistics in your response and provide the necessary hypotheses. (Provide the code used and relevant output tables.)
