What is the formula needed to predict U.S. car crash fatality rate if there are 340 metric tons of import lemons from Mexico? (a) y - 16.52(340) - 0.003 (b) y = 16.52 - 0.003(340) cy - 16.52(340) - 0.003 (d) y = 16.52 - 0.003(340) State the correlation value that best represents the plot presented. (a) 0.94 (b) 0.88 (c) -0.88 (d) -0.94 Interpret the slope of the line. (a) For a 1% increase in U.S. car crash fatality rate, imported lemons will, on average, decrease by 0.003 m (b) For a 1% increase in U.S. car crash fatality rate, imported lemons will, on average, increase by 16.5 me (c) For a 1 metric ton increase in imported lemons, U.S. car crash fatality rate will, on average, decrease d) For a 1 metric ton increase in imported lemons, U.S. car crash fatality rate will, on average, increase (e) We should not interpret the slope in this problem. Interpret the y-intercept of the line. (a) On average, when z = 0, there are 16.5 metric tons of imported lemons. (b) On average, when r = 0, there are -0.003 metric tons of imported lemons. (c) On average, when r = 0, the U.S. car crash fatality rate is 16.5%- (d) We should interpret y-intercept but none of the above are correct. e) We should not interpret the y-intercept in this
