2. Using the normal curve for descriptions of empirical distributions The National Assessment of Educational Progress (NAEP) is a nationwide assessment of students' proficiency in nine subjects: mathematics, reading, writing, science, the arts, civics, economics, geography, and U.S. history. The main NAEP assessments are conducted annually on samples of students from grades 4, 8, and 12. Suppose in 1994, the U.S. history scores for male students had a mean of 259 with a standard deviation of 33. Assume that these scores are normally distributed with the given mean and standard deviation. The normal curve representing this distribution of the scores is symmetrical about a vertical line through below the mean, and the value 325 is The value 193 is under the curve between 193 and 325 is approximately Similarly, 68.26% of the male students scored between and above the mean.
