Homework Answers
Mean test score = (84+78+84+72)/4 = 79.5
Weighted mean = Sum of (Score x weightage)
= 79.5x0.40 + 78x0.30 + 86x0.10 + 87x0.20
= 81.2
Weighted mean grade = 81.2

C ++ . In professor Maximillian’s course, each student takes four exams. A student’s letter grade is determined by first calculating her weighted average as follows: (score1 + score2 + score3 + score4 + max_score) weighted_average = ----------------------------------------------------------------------- 5 This counts her maximum score twice as much as each of the other scores. Her letter grade is then a A if weighted average is at least 90, a B if weighted average is at least 80...
