# Question: The following table gives the number of organ transplants performed

The following table gives the number of organ transplants performed in the United States each year from 1990 to 1999 (The Organ Procurement and Transplantation Network, 2003):

a. Construct a scatterplot of these data, and then find the equation of the least-squares regression line that describes the relationship between y = number of transplants performed and x = year. Describe how the number of transplants performed has changed over time from 1990 to 1999.

b. Compute the 10 residuals, and construct a residual plot. Are there any features of the residual plot that indicate that the relationship between year and number of transplants performed would be better described by a curve rather than a line? Explain.
