Answer:
he will need 224 yards of string
Step-by-step explanation:
56 ballons *12 feet=672 feet
each yard is 3 feet so he will need
1yard--->3feet
X<-------672feet=224 yards
It will be 89 because 27+17+15+13+8+3+6
The sample size suggested by this statement is 664 option second is correct.
<h3>What is the margin of error(MOE)?</h3>
It is defined as an error that provides an estimate of the percentage of errors in real statistical data.
The formula for finding the MOE:

Where Z is the z-score at the confidence interval
s is the standard deviation
n is the number of samples.
At 99% confidence Z = 2.576
By using the MOE formula:
0.05 = 2.376×√(0.5(0.5)/n)
After calculating
n = 663.57 ≈ 664
Thus, the sample size suggested by this statement is 664 option second is correct.
