You are to build a grading app for an instructor who needs to enter a. Exam #1 Score (0-50 points), b. Exam #2 Score (0-50 points), c. Exam #3 Score (0-50 points), d. Exam #4 Score (0-50 points), Assignment #1 Score (0-75 points), Assignment #2 Score (0-75 points), e. f. g. Assignment #3 Score (0-75 points), h. Assignment #4 Score (0-75 points). After entering all the scores, the maximum scores one student can get is 500. Based on the criteria given below, print the grade for the instructor. FinalScore >: 450 : "A", FinalScore>-400: "B", FinalScore> :350: "C", FinalScorea 300: "D", Else : "F" However, since the instructor is very generous, he wants to give better grades to the students based on the statistics of the students (this is an example only, not an actual case with you!). Say, the distribution of the total points of 10 students are 400 350 370 280 300 290 310 340 350 330 Then, the criterion of the grade A is A: Average of the students + (2x Standard Deviation of the students) B: >= Average of the students + (1x Standard Deviation of the students) (but less than A.) C: >= Average of the students (but less than "B") D: Average of the students-(1x Standard Deviation of the students) (but less than-e) F: : 450 : "A", FinalScore>-400: "B", FinalScore> :350: "C", FinalScorea 300: "D", Else : "F" However, since the instructor is very generous, he wants to give better grades to the students based on the statistics of the students (this is an example only, not an actual case with you!).
