An education researcher has been studying test anxiety using a particular measure, which she administers to students prior to midterm exams. On this measure, she has found that the distribution follows a normal curve. The measure has a mean of 13 and a standard deviation of 4. Using the accompanying normal curve table, what percentage of students have scores (a) above 22, (b) above 20, (c) above 19, (d) below 19, and (e) below 4?
