ANSWER:Solution 5CRE Step1: From the given problem we have the numbers of registered pleasure boats (thousands) in Florida and the numbers of watercraft-related manatee deaths for each year of the past decade. boats 90 92 94 95 97 99 99 97 95 Manatee deaths 91 95 73 69 79 92 73 90 97 Step2: Our aim is to find 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 pr
