The table below lists the numbers of registered pleasure boats (thousands) in Florida and the numbers of watercraft-related manatee deaths for each year of the past decade.

a. Test for a linear correlation between the numbers of boats and the numbers of manatee deaths.
b. Find the equation of the regression line. Use the numbers of boats for the independent x variable.
c. What is the best predicted number of manatee deaths for the year preceding those included in the table? For that year, there were 84 (thousand) registered pleasure boats in Florida. How accurate is that predicted value, given that there were actually 78 manatee deaths in that year?
