Every confidence interval has associated z value. As confidence interval increases so do the z value associated with it.
The confidence interval can be calculated using following formula:

Where

is the mean value, z is the associated z value, s is the standard deviation and n is the number of samples.
We know that standard deviation is simply a square root of variance:

The confidence interval of 95% has associated z value of <span>1.960.
</span>Now we can calculate the confidence interval for our income:

Step-by-step explanation:
Answer:
G = 2/3
Step-by-step explanation:
-13G + 10 = 2(-5G + 4) Distribute the 2 to (-5G + 4)
-13G + 10 = -10G + 8
+13G +13G Add 13G to both sides
10 = 3G + 8
-8 -8 Subtract 8 from both sides
2 = 3G Divide both sides by 3
2/3 = G
