Suppose your course grade is based on four quizzes and one final exam.

Each quiz counts as 15% of your final grade, and the final counts as 40%.

Your quiz scores are 75, 80, 84, and 88, and your final exam score is 96.

What is your overall score?

Because the weights are percentages in the course grade example, we could think of the weights as 0.15 and 0.40 rather than 15% and 40%.

Calculate the weighted mean by using the weights of 0.15 and 0.40. Do you still find the same answer? Why or why not?
