Essay

An experiment is conducted to investigate how the behavior of mozzarella cheese varied with temperature. Consider the accompanying data on x = temperature and y = elongation (%) at failure of the cheese. $$\begin{array} { c c c c c c c c } \hline x & 59 & 63 & 67 & 72 & 74 & 78 & 83 \\\hline y & 118 & 182 & 247 & 208 & 197 & 160 & 132 \\\hline\end{array}$$
a. Construct a scatter plot in which the axes intersect at (0,0). Mark 0, 20, 40, 60, 80, and 100 on the horizontal axis and 0, 50, 100, 150, 200, and 250 on the vertical axis.
b. Construct a scatter plot in which the axes intersect at (55,100). Does this plot seem preferable to the one in part (a)? Explain your reasoning.
c. What do the plots of parts (a) and (b) suggest about the nature of the relationship between the two variables?
