Combine the data from the two: e. Prepare the analysis table manually (Show ALL Working) f. State the null hypothesis(es), the decision rule for a=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 assumption of normality and homogeneity of variance was violated. Carefully discuss your findings quoting relevant statistics in your response and provide the necessary hypotheses. (Provide the code and the relevant output tables)
