Right off the bat (haha), we can eliminate B as an answer choice because adults are clearly part of the population; in fact, it says in the background information that their entire population is made of adults.  A population, in this context, is the group being researched.

D isn't the correct answer; the fact that adults are the target population doesn't validify anything.

C doesn't entirely prove its point because there are other factors that go into the game being biased.  In fact, I would say that this study <em>is </em>biased because the board members only attended 1 game when there are 18 teams.  Their data will only pertain to fans of the 2 teams playing each other, and not represent the population as a whole.

A would be my answer for reasons stated above.

Calculate the annual return percentage
const2013 [10]
The annual returns will be calculated as follows:
a] Here we use the formula:
A=p(1+r/100)^n
A=future amount
p=principle
r=returns
n=time
We are given:
A=500, p=400, t=1
Plugging the values in the formula we obtain:
500=400(1+r)^1
simplifying and solving for r:
1.25=1+r
thus
r=1.25-1
r=0.25~25%

b] Using the formula above:
A=p(1+r/100)^n
A=2500+100=2600, p=2000, n=1 year
plugging the values in the equation we obtain:
2600=2000(1+r)^1
simplifying and solving for r we obtain:
2600/2000=1+r
1.3=1+r
hence
r=1.3-1
r=0.3~30%
