Answer:
89.84375
Step-by-step explanation:
Given that on a finance exam, 15 accounting majors had an average grade of 90. On the same exam, 7 marketing majors averaged 85, and 10 finance majors averaged 93.
To find weighted mean.
Here weights can be considered as number of majors in each subject
![Marks x 90 85 93\\Weights 15 7 10\\Product 1350 595 930\\](https://tex.z-dn.net/?f=Marks%20x%20%20%20%20%2090%20%20%20%20%20%20%20%2085%20%20%20%20%20%20%2093%5C%5CWeights%20%20%20%20%2015%20%20%20%20%20%20%20%20%20%207%20%20%20%20%20%20%20%20%2010%5C%5CProduct%20%20%20%20%201350%20%20%20%20595%20%20%20%20%20930%5C%5C)
Weighted total = 1350+595+930 = 2875
Weighted mean = weighted total/total students
![=\frac{2875}{32} =89.84375](https://tex.z-dn.net/?f=%3D%5Cfrac%7B2875%7D%7B32%7D%20%3D89.84375)
