Answer:
86
Step-by-step explanation:
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:
2 (1/3) cups
Step-by-step explanation:
8 x 3(1/2) = 28 cups
28 / 12 = 2 (1/3) cups
