2. Suppose SAT scores roughly follows a normal distribution in the U.S. population of college-bound students (with range restricted to 200- 800), and the average math SAT is 525 with a standard deviation of 60, then solve for the area under the curve of the following interval of scores between : i. 370 and 625 ii. 400 and 600 iii. 350 and 650
