Considering the margin of error, it is found that the 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).
<h3>What is a confidence interval?</h3>
It is given by the sample statistic plus/minus the margin of error.
In this problem, 68% of adults say such vaccines should be required, with a margin of error of 3.1%, hence:
68% - 3.1% = 64.9%.
68% + 3.1% = 71.1%.
The 95% confidence interval for the percentage of adults who say vaccines should be required is (64.9%, 71.1%).

What is 6 times 5 squared? Simply write that out. Then, remember that in PEMDAS, you solve the exponent before you multiply. That will give you the value. Hope this helps!
<span>27,?,?,?,53,... has a common difference of (53 - 27) / 4, or 6.5.
27
27 + 6.5 = 33.5
33.5 + 6.5 = 40
40 + 6.5 = 46.5
46.5 + 6.5 = 53
Each new term is equal to the previous term plus 6.5.
