Answer:
(b)
We can use an estimatior for the population proportion as
since we don't know previous info. And replacing into equation (b) the values from part a we got:
And rounded up we have that n=1068
Step-by-step explanation:
In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since the confidence level is 99%, our significance level would be given by
and
. And the critical value would be given by:
The margin of error for the proportion interval is given by this formula:
(a)
And on this case we have that
and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)

Step-by-step explanation:
Fifth Root is given by:
![\sqrt[5]{z}=1+0i](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bz%7D%3D1%2B0i)
The above equation will become:

It can be written as:
![z=[cos(0)+isin(0)]^5](https://tex.z-dn.net/?f=z%3D%5Bcos%280%29%2Bisin%280%29%5D%5E5)
|z|=1,
According to De-moivre's Theorem:

Now, Fifth Roots of unity in standard form a + bi :
![\sqrt[5]{z}=[{cos(0+2\pi k)+isin(0+2\pi k)}]^{1/5}](https://tex.z-dn.net/?f=%5Csqrt%5B5%5D%7Bz%7D%3D%5B%7Bcos%280%2B2%5Cpi%20k%29%2Bisin%280%2B2%5Cpi%20k%29%7D%5D%5E%7B1%2F5%7D)
k=0,1,2,3,4
