14 feet long. ............
Answer:
The margin of error is given below:
![E=z \times \sqrt{\frac{\hat{p}(1-\hat{p}}{n} }](https://tex.z-dn.net/?f=E%3Dz%20%5Ctimes%20%5Csqrt%7B%5Cfrac%7B%5Chat%7Bp%7D%281-%5Chat%7Bp%7D%7D%7Bn%7D%20%7D)
Where:
![\hat{p}=\frac{26}{80}=0.325](https://tex.z-dn.net/?f=%5Chat%7Bp%7D%3D%5Cfrac%7B26%7D%7B80%7D%3D0.325)
![\therefore E = z \times \sqrt{\frac{0.325(1-0.325}{80} }](https://tex.z-dn.net/?f=%5Ctherefore%20E%20%3D%20z%20%5Ctimes%20%5Csqrt%7B%5Cfrac%7B0.325%281-0.325%7D%7B80%7D%20%7D)
![=z \times 0.0523659](https://tex.z-dn.net/?f=%3Dz%20%5Ctimes%200.0523659)
Therefore, the option E = z*6% is correct as it closest to the given answer
