A power is also an exponent which is how many times you multiply a number by itself to get a product
To get 100 as a product of 10 times itself you would multiply 10x10 which is the same as 10^2
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:
![\hat p_1 = \frac{x_1}{n_1}](https://tex.z-dn.net/?f=%5Chat%20p_1%20%3D%20%5Cfrac%7Bx_1%7D%7Bn_1%7D)
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:
![\hat p_2 = \frac{x_2}{n_2}](https://tex.z-dn.net/?f=%5Chat%20p_2%20%3D%20%5Cfrac%7Bx_2%7D%7Bn_2%7D)
For this case we know that the true proportion is ![p](https://tex.z-dn.net/?f=p)
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.
102
the angles are alternate so they add up to 180
180-78=102
hope this helps :)
if you need me to explain more just let me know :)
