Statistics

The National Highway Traffic Safety Administration analyzes the crash test data for new cars. One variable measured is the severity of the injury due to a collision. The higher the severity, the higher the points assigned. Assume that the injury rating is normally distributed with a mean (ì) of 605 points and a standard deviation (ó) of 185 points. One of the crash-test cars is randomly selected from the data and its rating is observed.
Find the probability that the rating will fall between 500 and 700 points.

  1. Z = (score-mean)/SD

    Find table in the back of your statistics text labeled something like "areas under normal distribution" to find the proportion/probability from the mean for both Z scores. Add the two probabilities.
