Dr. Susan Marsh, a physician at the Health Living Community Center, would like to obtain a better understanding of the factors that contribute to obesity in the community. Engaging research has suggested that proximity to convenience stores may be a contributing factor to obesity. To test this argument, she asks one of her assistants to collect data for a sample of 50 randomly selected male clients. The first variable collected is the distance of each clients' home to the nearest convenience store (in miles, DISTANCE), and the second variable for the analysis if client weight (WEIGHT). Use the data in the Excel spreadsheet to (1) draw a scatter plot, (2) calculate the correlation coefficient between the two variables, and (3) interpret the coefficient. Based on these findings, can you conclude that proximity to convenience stores leads to obesity?
