Answer:
I don't know which school you are asking for, so here are all of them, followed by the general mean of all the schools.
a: 1.7
b: 4.7
c: 3.9
d: 5.3
e: 4.5
gen: 4
Step-by-step explanation:
This is easiest to solve with a calculator.
When finding the mean, you need to add all the numbers together, then divide by how many numbers you added.
Let's say that you have the numbers 2, 5, and 8. You add them together to get 15, then divide 15 by 3. The mean is 5.
With your problem, the general mean of all 5 schools is 4.
Hope that this helps!
