A scatter plot is the best choice for presenting the data as it can effectively display the relationship between the two variables (approximate retail price and energy cost per year) for each of the 15 refrigerators. It allows for visualization of any potential patterns or trends in the data, such as whether higher-priced refrigerators tend to have higher or lower energy costs. A pie chart would not be appropriate as it is not suitable for displaying numerical data with multiple categories. A side-by-side bar chart could work but may not be as effective as a scatter plot in displaying the relationship between the two variables. A contingency table is not relevant as it is used for displaying the counts or proportions of observations falling into two or more categorical variables.
