Question

Fast food is often considered unhealthy due to high levels of fat and sodium. In order to verify if the two variables are associated, data on fat content and sodium content of hamburgers from a sample of 5 fast food restaurants were obtained, and the data are summarized in the table below: Fat Content (g) Sodium Content (mg) 10 530 8 510 11 560 18 640 14 390 x? = 12.2 ? = 526 Sx = 3.90 Sy = 90.72 Given that the correlation coefficient which relates fat content and sodium content in hamburgers is r = 0.307, the value of the RMS of the regression equation is ____. A) 75.52 B) 1.20 C) 27.85 D) 86.34 E) 3.71
