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 54 and a standard deviation of 15. Using the accompanying normal curve table, what percentage of students have scores (a) above 72, (b) above 57, (C) above 81, (d) below 81, and (e) below 36? Click here to view page 1 of the normal curve table, Click here to view page 2 of the normal curve table, Click here to view page 3 of the normal curve table. Click here to view page 4 of the normal curve table. .... (a) % of students have scores above 72. (Round to two decimal places as needed.) (b) % of students have scores above 57. (Round to two decimal places as needed.) (c) % of students have scores above 81. (Round to two decimal places as needed.) (d) % of students have scores below 81. (Round to two decimal places as needed.) (e)% of students have scores below 36. (Round to two decimal places as needed.)
