A regression was run to determine if there is a relationship between hours of TV watched per day (x) and number of situps a person can do (y). The results of the regression were: y=ax+b a=-0.859 b-37.904 r²-0.589824 r=-0.768 Use this to predict the number of situps a person who watches 11.5 hours of TV can do (to one decimal place)

The figure plots the number of manatee deaths by boat versus the number of boats registered to Florida and thousands. There is a clear straight line pattern with a modest amount of scatter. The correlation between these variables is R equals 0.94. What percentage of the observed variation among the manatee deaths by boats is explained by the straight line relationship between manatee deaths and number of boats registered?
