The table shows the combined city and highway fuel efficiency (in miles per gallon gasoline equivalent) and top speeds (in miles per hour) for nine hybrid and electric cars. a) Find the coefficient of determination $$r^2$$ and interpret the result. b) Find the standard error of estimate se and interpret the result. c) Find the regression equation and graph the regression line with scatter plot to interpret the result. d) Use the regression equation to predict the values of $$y$$ for $$x=130$$ and $$x=75$$, if meaningful. If the $$x$$ values are not meaningful to predict the values of $$y$$, explain why not. e) Construct a $$90\%$$ prediction interval for the top speeds when the average fuel efficiency is 100 miles per gallon.
