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. To learn more about the Web site customers, a sample of 50 Heavenly Chocolate transactions was selected from the previous month’s sales. Data showing the day of the week each transaction was made, the type of browser the customer used, the time spent on the Web site, the number of Web site pages viewed, and the amount spent by each of the 50 customers are contained in the file named Shoppers. A portion of the data is shown in the table that follows:

Customer Day Browser Time (Min) Pages Viewed Amount Spent ($
1 Mon IE 12 4 54.52
2 Wed Other 19.5 6 94.9
3 Mon IE 8.5 4 26.68
4 Tues Firefox 11.4 2 44.73
5 Wed IE 11.3 4 66.27

48 Fri IE 9.7 5 103.15
49 Mon Other 7.3 6 52.15
50 Fri IE 13.4 3 98.75

Required:
a. Develop a scatter diagram, and compute the sample correlation coefficient to explore the relationship between the time spent on the Web site and the dollar amount spent. Use the horizontal axis for the time spent on the Web site. Discuss.
