# Statistics

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 15% of your total grade, each major test is worth 22.5%, and the final exam is worth 40%. Compute the weighted average for the following scores: 88 on the lab, 76 on the first major test, 63 on the second major test, and 100 on the final exam. (Round your answer to one decimal place.)

1. Is the final grade based on the cumulative amount or an average?

Cumulative

.15(88) + .225(76+63) + .4(100) = ?

Average

[.15(88) + .225(76+63) + .4(100)]/4 = ?
