Manatees are large: gentle sea creatures that live along the Florida coast. Many manatees are killed or injured by boats In Florida. manatee deaths from powerboat encounters have been at the center of considerable controversy between environmentalists and boat operators. Here are data on registered Florida Pleasure Craft (in tens of thousands) and watercraft-related manatee deaths in Florida in the years 1991 to 2000: Pleasure Craft Manatee Year Registrations Deaths (in tens of thousands) 1 991 68 53 1 992 68 38 1 993 6? 35 1 994 70 49 1 995 T1 42 1 996 7'3 60 1 997 76 54 1 998 81 67 1 999 83 82 2000 84 73 We want to examine the relationship between the number of pleasure boats registered and the number of manatees killed by boats. \fGraph your line on your scatterplot.
