Suppose there is a normally distributed population which has amean of ? = 440and a standard deviation of ? = 60. (15p)
1.What portion of a normal distribution is below 295?
2. What z-score would correspond to a raw score of 260?
3. What raw score would correspond to a z score of -3.5?
4. If we randomly select one score from this population, what isthe probability that will be less than 550?
5. If we randomly select one score from this population, what isthe probability that will be greater than 580?
