There is a relationship between confidence interval and standard deviation:
Where
is the mean, 
is standard deviation, and n is number of data points.
Every confidence interval has associated z value. This can be found online.
We need to find the standard deviation first:
When we do all the calculations we find that:
Now we can find confidence intervals:
We can see that as confidence interval increases so does the error margin. Z values accociated with each confidence intreval also get bigger as confidence interval increases.
Here is the link to the spreadsheet with standard deviation calculation:

Answer:
Step-by-step explanation:
Hello!
We can use the factored form of a Quadratic to find an equation with 8 and -8 as our solution.
<h3>Factored Form:The value in each parenthesis should be 0. So 8 and -8 can be flipped and used for h and k.
This will give roots 8 and -8 for x.
A possible equation is .
