A large chemistry course took their final exam. The mean was 75 with a standard deviation of 8. What are the exam scores that separate the top and bottom 5 percent of the class (extreme 10%)? What are the exams scores that separate the middle 10% of the class (5% on each side of the mean)? Use table below and draw normal distribution
