Answer:
The margin of error M.O.E = 2.5%
Step-by-step explanation:
Given that;
The sample size = 1500
The sample proportion
= 0.60
Confidencce interval = 0.95
The level of significance ∝ = 1 - C.I
= 1 - 0.95
= 0.05
The critical value:
(From the z tables)
The margin of error is calculated by using the formula:
![M.O.E = Z_{\alpha/2} \times \sqrt{\dfrac{\hat p(1 -\hat p)}{n}}](https://tex.z-dn.net/?f=M.O.E%20%3D%20Z_%7B%5Calpha%2F2%7D%20%5Ctimes%20%5Csqrt%7B%5Cdfrac%7B%5Chat%20p%281%20-%5Chat%20p%29%7D%7Bn%7D%7D)
![M.O.E = 1.96 \times \sqrt{\dfrac{\hat 0.60(1 -0.60)}{1500}}](https://tex.z-dn.net/?f=M.O.E%20%3D%201.96%20%5Ctimes%20%5Csqrt%7B%5Cdfrac%7B%5Chat%200.60%281%20-0.60%29%7D%7B1500%7D%7D)
![M.O.E = 1.96 \times \sqrt{\dfrac{0.24}{1500}}](https://tex.z-dn.net/?f=M.O.E%20%3D%201.96%20%5Ctimes%20%5Csqrt%7B%5Cdfrac%7B0.24%7D%7B1500%7D%7D)
![M.O.E = 1.96 \times \sqrt{1.6 \times 10^{-4}}](https://tex.z-dn.net/?f=M.O.E%20%3D%201.96%20%5Ctimes%20%5Csqrt%7B1.6%20%5Ctimes%2010%5E%7B-4%7D%7D)
M.O.E = 0.02479
M.O.E ≅ 0.025
The margin of error M.O.E = 2.5%
Answer: B
Step-by-step explanation: if you divide 27/30 by 3 you get 9/10
