Suppose you have magically changed places with the professor teaching this course and that you have just administered an examination that consists of 100 multiple-choice items (where 1 point is awarded for each correct answer). The distribution of scores for the 25 students enrolled in your class could theoretically range from 0 (none correct) to 100 (all correct). Below are your student's scores. You will use this raw data to complete all of the calculations in this assignment: Student. Score.
