Answer:
 
 
And we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
Step-by-step explanation:
The estimated proportion of interest is 
We need to find a critical value for the confidence interval using the normla standard distributon. For this case we have 95% of confidence, then the significance level would be given by  and
 and  . And the critical value is:
. And the critical value is:
 
The confidence interval for the true population proportion is interest is given by this formula:  
 
Replacing the values provided we got:
 
 
And we can conclude at 95% of confidence that the true proportion of interest for this case is between 0.287 and 0.613
