Draw a normal distribution curve and find the percentage of the bounded regions in each item. A large group of students took a test in General Chemistry and the final grades have a mean of 70 and a standard deviation of 10. if we can approximate the distribution, what percent of the students a.) scored higher than 80? b.) should pass the test (grades ≥ 60) c.) should fail the test (grades < 60)?
