Answer:
V>-8
Step-by-step explanation:
The given inequality is :
4-V>12
Subtracting 4 from both sides.
4-V-4 > 12-4
-V>8
or
V>-8
So, the value of V is more than -8.
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
