The scores and their percent of the final grade for a statistics student are given. What is the student's weighted mean score?

Phantasy [73]

Answer:

The student's weighted mean score is 92.2.

Step-by-step explanation:

To find the student's weighted mean scored, we multiply each grade by it's weight.

Grades and weights:

Homework: Grade of 86, weight of 20% = 0.2

Quiz: Grade of 87, weight of 5% = 0.05

Quiz: Grade of 91, weight of 5% = 0.05

Project: Grade of 98, weight of 45% = 0.45

Final Exam: Grade of 88, weight of 25% = 0.25.

What is the student's weighted mean score?

0.2*86 + 0.05*87 + 0.05*91 + 0.45*98 + 0.25*88 = 92.2

The student's weighted mean score is 92.2.
