Overview
Heavenly Chocolates manufactures and sells quality chocolate products at its plant and retail store located in Saratoga Springs, New York. Two years ago, the company developed a web site and began selling its products over the Internet. Web site sales have exceeded the company’s expectations, and management is now considering strategies to increase sales even further.

3. Develop a scatter chart, and compute the sample correlation coefficient to explore the
relationship between the time spent on the web site vs. the dollar amount spent, as well as web
