9 divided by 4 is 2.25 hope this helped!
Answer: The required confidence interval is (56.1,66.9).
Since we have given that
53.1, 60.2, 60.6, 62.1, 64.4, 68.6
n = 6
Margin of error = 5.4
At 95% level of confidence, z = 1.96
So, the confidence interval would be
Hence, the required confidence interval is (56.1,66.9).
r = 45A = 6361.7
x^2 + y^2 = 2025this is a circleroot 2025 will give the radiusroot 2025 = 45pi * 2025 will give the areaA = 6361.7
