Short Answer

Annual measurements of the number of powerboat registrations (in thousands) and the number of manatees killed by powerboats in Florida were collected over the 14 years 1977-1990. A scatterplot of the data, least squares regression line, and correlation coefficient follow.
-The year 1984 had 559,000 powerboat registrations and 34 manatee deaths. Calculate the residual for this observation.
