Answer:
Open dot going to the right on the number 2.
Step-by-step explanation:
If the > sign or the < sign has a line under it (meaning < or equal to number or > or equal to number), it is a closed dot. If it doesn’t the dot is open. This is because if the dot is closed then it is a solution, and vice versa. If m > 2, then m would be an open dot (not a solution to equation) going to the right (greater than number)

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).
