2. To analyze the total number of items purchased, construct an UNGROUPED frequency distribution, graph, and find the summary statistics (including the quartiles) by each type of customer (regular/promotion). Label the graphs completely. Describe the shape of the distribution for each type of customer, and discuss similarities or differences by interpreting the graphs and summary statistics. What can you conclude?
