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 (f) What would you predict for takeoff velocity (in meters per second) for a salamander jumping with a bend angle of 50 degrees? (Round your answer to two decimal places.) Enter a number. m/s (g) What would you predict for takeoff velocity (in meters per second) for a salamander jumping with a bend angle of 65 degrees? (Round your answer to two decimal places.) Enter a number. m/s (h) What would you predict for takeoff velocity (in meters per second) for a salamander jumping with a bend angle of 90 degrees? (Round your answer to two decimal places.) Enter a number. m/s Would you consider the predicted takeoff velocity for a salamander jumping with a bend angle of 90 degrees reliable? Explain
