1. Describe the characteristics of the normal curve. (2 points)
2. SAT-Math scores are normally distributed with a mean of 500 and standard deviation of 100. We can treat these values as population values, m = 500 and s = 100. Use these values to solve the following problems:
(a) For a student with a math SAT-Math score of 590, convert their SAT score to a z score. (2 points)
(b) What percentage of students would have a SAT-Math score greater than 590? (2 points)
(c) What percent of students would be expected to have a SAT-Math score between 450 and 550? (2 points)
(d) What is the probability of having a SAT-Math score less than 540? (2 points)
