Using the z-distribution, it is found that the 90% confidence interval for the proportion of Americans who believe that the minimum wage should be raised is (0.4689, 0.5311).
<h3>Confidence interval of a proportion</h3>
- In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following <em>confidence interval of proportions.</em>
- In which z is the z-score that has a p-value of
.
In this problem:
- 350 out of 700 in the sample said yes, hence
.
- 90% confidence level, hence
, z is the value of Z that has a p-value of
, so
.
The lower limit of this interval is:
The upper limit of this interval is:
The 90% confidence interval for the proportion of Americans who believe that the minimum wage should be raised is (0.4689, 0.5311).
