Answer: 18
Step-by-step explanation:
The formula to find the minimum sample size is given by :_
, where 
= population standard deviation.
z*= critical z-value.
E= Margin of error.
Given : 
E= ± 8
We know that critical value corresponding to 99% confidence level = z*=2.576 [Using z-table]
Then, the required sample size would be :
[Round to next integer.]
Hence, the required minimum sample size = 18
Answer:
x = -3
Step-by-step explanation:
5 = x + 8
You need to get x by Itself so subtract 8 to both sides.
5 - 8 = -3
so therefore x = - 3
