What is the average lab report grade for this student?

(round to the hundredths place)

Add the lab report grades and divide by 8. For your question, the quiz, exam and research paper data are unnecessary.

To find the average lab report grade for this student, you need to calculate the mean of the lab report grades.

Adding up the lab report grades:
75 + 80 + 70 + 75 + 85 + 69 + 90 + 75 = 599

Dividing the total by the number of lab reports:
599 / 8 = 74.875

Therefore, the average lab report grade for this student is approximately 74.88.
