Question:
Consumer Reports Health (www. consumerreports. org) gave the following data on saturated fat ( in grams), sodium ( in mg), and calories for 36 fast- food items. a. Construct a scatterplot using y 5 calories and x 5 fat. Does it look like there is a relationship between fat and calories? Is the relationship what you expected? Explain. b. Construct a scatterplot using y 5 calories and x 5 sodium. Write a few sentences commenting on the dif-ference between this scatterplot and the scatterplot from Part ( a). c. Construct a scatterplot using y 5 sodium and x 5 fat. Does there appear to be a relationship between fat and sodium? d. Add a vertical line at x 5 3 and a horizontal line at y 5 900 to the scatterplot in Part ( c). This divides the scat-terplot into four regions, with some points falling into each region. Which of the four regions corresponds to healthier fast- food choices? Explain.
