Course Hero a Join Prime Today The ability to jump helps salamanders move quickly to avoid predators. A paper investigated jumping behavior of 10 species of salamanders and reported the following data on bend angle (the bend [in degrees] in the salamander body, with a larger number reflecting more extreme bending) and the jump takeoff velocity (in meters per second). There is a positive correlation between bend angle and takeoff velocity Bend Angle Takeoff Velocity 36.4 0.6 55.1 0.7 43.6 0.7 50.3 0.7 69.9 0.9 71.1 1.0 67.5 1.1 48.2 0.7 61.9 0.9 52.7 0.9 (a) If the goal is to learn about how takeoff velocity is related to salamander bend angle, which of these two variables is the response variable and which is the predictor variable? OThe predictor variable (x) is bend angle and the response variable (y) is takeoff velocity. OThe predictor variable (x) is takeoff velocity and the response variable (y) is bend angle. (b) Construct a scatterplot of these data. Would it be reasonable to use a line to summarize the relationship between takeoff velocity and bend angle? It would not be reasonable to use a line to summarize the relationship between takeoff velocity and bend angle. It would be reasonable to use a line to summarize the relationship between takeoff velocity and bend angle. (c) Find the equation of the least squares regression line. (Round your numerical values to four decimal places.) y = (d) Interpret the slope of the least squares regression line in the context of this study. O The slope is the average takeoff velocity when the bend angle is 0.v
