Answer:
A sample of 16577 is required.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of  , and a confidence level of
, and a confidence level of  , we have the following confidence interval of proportions.
, we have the following confidence interval of proportions.

In which
z is the z-score that has a p-value of  .
.
The margin of error is of:

99% confidence level
So  , z is the value of Z that has a p-value of
, z is the value of Z that has a p-value of  , so
, so  .
. 
She wants to estimate the proportion using a 99% confidence interval with a margin of error of at most 0.01. How large a sample size would be required?
We have no estimation for the proportion, and thus we use  , which is when the largest sample size will be needed.
, which is when the largest sample size will be needed.
The sample size is n for which M = 0.01. So






Rounding up:
A sample of 16577 is required.
 
        
             
        
        
        
Answer: (0.076, 0.140)
Step-by-step explanation:
Confidence interval for population proportion (p) is given by :-

 , where  = sample proportion.
 = sample proportion.
n= sample size.
 = significance level .
 = significance level .
 = critical z-value (Two tailed)
 = critical z-value (Two tailed)
As per given , we have
sample size : n= 500
The number of Independents.:  x= 54
Sample proportion of Independents
Significance level 98% confidence level :  
 
By using z-table , Critical value :  
 
The 98% confidence interval for the true percentage of Independents among Haywards 50,000 registered voters will be :-

Hence, the 98% confidence interval for the true percentage of Independents among Haywards 50,000 registered voters.= (0.076, 0.140)
