1. Given u = 55, o = 2.15, find z value that correspond to the score of 60. 2. Given u = 80, o = 7, find the score that correspond z = -1.15. 3. What z score associated with Percentile 55? 4. A Gen. Math Teacher gave a comprehensive final exam that is normally distributed with a mean of 150 points and o = 25 points. What is the percentile rank of the students with a score of 160 points? 5. Suppose there are 10,000 test takers of the IQ test where the mean is 100 and the standard deviation of 15. What is the raw score that correspond to each of the following z scores:
