Problem 5

The article Objective Measurement of the Stretchabilityof Mozzarella Cheese (J. of Texture Studies, 1992:185194) reported on an experiment to investigate how thebehavior of mozzarella cheese varied with temperature.Consider the accompanying data on x 5 temperature andy 5 elongation(%) at failure of the cheese. [Note: The researchers were Italian and used real mozzarella cheese,not the poor cousin widely available in the United States.]x 59 63 68 72 74 78 83y 118 182 247 208 197 135 132a. Construct a scatterplot in which the axes intersectat (0, 0). Mark 0, 20, 40, 60, 80, and 100 on thehorizontal axis and 0, 50, 100, 150, 200, and 250on the vertical axis.b. Construct a scatterplot in which the axes intersectat (55, 100), as was done in the cited article. Doesthis plot seem preferable to the one in part (a)?Explain your reasoning.c. What do the plots of parts (a) and (b) suggest aboutthe nature of the relationship between the twovariables?
