Answer:
The sample needed is 
Step-by-step explanation:
From the question we are told that
The margin of error is 
The confidence level is 
Given that the confidence level is 95% the level of significance is mathematically represented as
Next we obtain the critical value of 
from the z-table , the value is 
The reason we are obtaining critical value of instead of 
is because
represents the area under the normal curve where the confidence level interval (
) did not cover which include both the left and right tail while
is just the area of one tail which what we required to calculate the margin of error
The sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \r p[1-\r p]](https://tex.z-dn.net/?f=n%20%20%3D%20%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%7D%7BE%7D%20%5D%5E2%20%2A%20%5Cr%20p%5B1-%5Cr%20p%5D)
Here 
is sample proportion of people that supported her and we will assume this to be 50% = 0.5
So
![n = [\frac{1.96}{ 0.08} ]^2 * [0.5 (1- 0.5)]](https://tex.z-dn.net/?f=n%20%20%3D%20%5B%5Cfrac%7B1.96%7D%7B%200.08%7D%20%5D%5E2%20%2A%20%20%5B0.5%20%281-%200.5%29%5D)
I’m sorry but there’s no question I can answer put a question down and I can I’m happy to help u with any other questions :)
