5. Dne of the variables measured in an automobile crash test is the severity of the driver's head injury when the car is in a head-on collision with a fixed barrier while traveling at 35mph. The higher the rating, the more severe the injury. The head injury ratings are approximately normal with a mean of B10 points and a standard deviation of 175 points. (2 points) a. What is the standardized score ( z-score) of a randomly selected crash test head injury with a rating of 600 points?b. Shade in the appropriate area on the diagram and find the probability that a randomly selected crash tes head injury will have a rating of exactly 600 points. Shade in the appropriate area on the diagram and find the probability that a randomly selected crash test head injury will have a rating between 650 and 700 points..
