(Hypothetical.) At a large university, assume the average Math SAT score of all students is 450 with a standard deviation of 85. For a survey, we will randomly select 200 of the students. The expected value of the sum of the 200 students' scores is 450 with a standard error of 85 . The average student score is the sum of the scores, divided by the number of students. The expected value of the average of the 200 students' scores is with a standard error of .
