Answer:
Since they use random sampling then we can conclude that the two estimators would be unbiased of the real parameter.
So then the best answer would be:
c. The sample proportion, ^p, in either proposal is equally likely to be close to the true population proportion, p, since the sampling is random.
Step-by-step explanation:
For this case we have a first sample size and from this sample we have people who anwswer yes and the estimated proportion of yes is given by:
And let a second sample size and from this sample we have people who anwswer yes and the estimated proportion of yes is given by:
For this case we know that the true proportion is

Answer:
Step-by-step explanation:
x + z + y = 60
- x + z + y = -6 <-- (x - z = y + 6)
x + 3z + y = 40
<em>cancel out the two equations (z minus each other and y minus each other)</em>
x + z + y = 60
- -x + z + y = -6

2x + 0 + 0 = 66
x = 33
