A stem-and-leaf display is the best choice for presenting the information because it allows for a clear and concise representation of the distribution of the data, showing each individual observation while also displaying the overall shape of the data. A pie chart would not be appropriate for displaying quantitative data, as it is better suited for showing percentages or proportions of categorical data. A Pareto chart could be useful for visualizing the frequency of certain credit hour ranges, but it would not be as informative as a stem-and-leaf display. A contingency table is used to display the joint distribution of two categorical variables, and therefore would not be applicable in this context.
