8) (20 points) Mature saltwater crocodiles have bite forces that are normally distributed, with a mean of 4,000 lbs (now that's a bite!) and standard deviation of 420 lbs. Draw a complete normal curve for each of the following. a) Find the lowest and highest bite force that contain the middle 85% of bite forces (use units) b) Find the probability that a randomly selected crocodile has a bite force between 3,000 lbs and 5,000 lbs c) The strongest 20% of crocodiles have a bite force above (use units)
