The Minimum sample size table is attached below
Answer:

Step-by-step explanation:
From the question we are told that:
Confidence Interval 
Variance 
Generally going through the table the
Minimum sample size is

<span>(5 2/3+8 1/4)+9 3/4=n+18
</span><span>5 2/3+8 1/4+9 3/4=n+18
</span>5 2/3 + 18 = n + 18 | - 18
5 2/3 = n
I would say to check the 1st and 3rd
Answer:
12
Step-by-step explanation:
(66 2/3)
---------- (x) = 8
100
Solve for x
(66 2/3)x = 800
x = 800/(66 2/3)
x = 800/(200/3)
x = 800(3/200)
x = 4(3)
x = 12
