Identifying Total Variation What percentage of the total variation in manatee fatalities can be explained by the linear correlation between registered boats and manatee fatalities?

Interpreting a Computer Display. In Exercises 9–12, refer to the display obtained by using the paired data consisting of Florida registered boats (tens of thousands) and numbers of manatee deaths from encounters with boats in Florida for different recent years (from Data Set 12 in Appendix B). Along with the paired boat ,manatee sample data, StatCrunch was also given the value of 85 (tens of thousands) boats to be used for predicting manatee fatalities.
