The numbers of cremations in the United States are shown in Table 18 for various years.

Let p be the percentage of bodies that are cremated in the year that is t years since 1990.
a. Construct a scatterplot.
b. Describe the four characteristics of the association. Compute and interpret r as part of your analysis.
c. Graph the model p = 1.40t + 11.96 on the scatterplot. Does it come close to the data points?
d. What is the slope? What does it mean in this situation?
e. Solve the equation p = 1.40t + 11.96 for t.
f. What is the slope of the model you found in part (e)? What does it mean in this situation?
