Answer:
B (0.312, 0.364)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence interval , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of
For this problem, we have that:
1289 randomly selected American adults responded to this question. This means that .
Of the respondents, 436 replied that America is doing about the right amount. This means that .
Determine a 95% confidence interval for the proportion of all the registered voters who will vote for the Republican Party.
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
The 95% confidence interval is:
B (0.312, 0.364)
