In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 19% of your total grade, each major test is worth 25%, and the final exam is worth 31%. Compute the weighted average for the following scores: 93 on the lab, 86 on the first major test, 94 on the second major test, and 88 on the final exam.
What is the weighted mean?
