Apply the rule (-x, y - 2) to the following point, what is the result?
2 answers:
Answer: Second Choice. (3, 3)
Step-by-step explanation:
<u>Given point</u>
(x, y) = (-3, 5)
<u>Given the rule for application</u>
(-x, y - 2)
<u>Determine the new x-value</u>
x = -3
-x = - (-3) = 3
<u>Determine the new y-value</u>
y = 5
y - 2 = (5) - 2 = 3
Therefore, the result is

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:
