Jennifer is a business student who is interning at a technology company. She has been tasked with analyzing the company's financial data to identify areas for improvement. Specifically, she has been asked to analyze the company's marketing expenses and determine if they are generating a positive return on investment (ROI). She has been provided with a dataset that includes the company's marketing expenses and sales revenue over the past year.

Jennifer should start by calculating the ROI for each of the company's marketing campaigns. She can then use data analysis tools to identify trends and patterns in the data. For example, she may find that certain types of marketing campaigns are generating a higher ROI than others. She can use decision-support tools, such as data visualization software, to present her findings to the company's management. She may also want to conduct a cost-benefit analysis to determine if the company should continue to invest in marketing or allocate resources to other areas of the business that may generate a higher ROI. By collecting, analyzing, and interpreting financial data, Jennifer can help the company make informed decisions that will improve its profitability and competitiveness.
