Table 64 describes countries€™ percentages of populations who are involved in producing agriculture and countries€™ per- person gross national product (GNP), which is a measure of the amount of goods and services a country produces.

Let y be the GNP per person (in dollars) for a country in which x percent of the population was involved in agriculture.
a. Construct a scatterplot.
b. Is the association positive, negative, or neither? What does that mean in this situation? Explain why this makes sense in terms of productivity.
c. Find a regression equation. Describe the shape and strength of the association.
d. What is the base b of your model = abx? What does it mean in this situation?
e. Which country€™s data point has the largest residual? What is the residual? What does the position of the point in relation to the other data points and the regression curve suggest about this situation?
