Assume that a .05 (2). Transform the data TransportationCost.csv to the data set with one dependent variable and one independent variable as two separate columns. Import the dataset you created. Construct a One-way ANOVA model using correct R command. Inspect the model. What is the p value? What is the statistical decision?Explanation / Answer
