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).

Answer:
slope = -
Step-by-step explanation:
Calculate the slope m using the slope formula
m =
with (x₁, y₁ ) = (- 5, 0) and (x₂, y₂ ) = (0, - 7 ) ← 2 points on the line
m = = = = -
12 is 20 % of the number 60<span>. Explanation: We can find derive this as the number we're looking for would be equals to </span>100<span>%.</span>
Not A or C because they are pretty much the same thing.
not B because to the nearest 0.25
so the last one left is D 14.25 inches
