Since OC is perpendicular to AB, the line AB gets split evenly. So
So AB=2*6.7=13.4
Ans: Option B, 13.4 units

Answer:The required interval is (0.196, 0.030).
Step-by-step explanation:
Since we have given that
n = 432
x = 108
So,
at 99% level of confidence, z = 2.576
So, Margin of error would be
So, margin of error = 0.0536
Now, confidence interval would be
Hence, the required interval is (0.196, 0.030).
