Answer:
Option d (7.84 or less) is the right alternative.
Step-by-step explanation:
Given:
![\sigma^2=1936](https://tex.z-dn.net/?f=%5Csigma%5E2%3D1936)
![\sigma = \sqrt{1936}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B1936%7D)
![=44](https://tex.z-dn.net/?f=%3D44)
Random sample,
![n = 121](https://tex.z-dn.net/?f=n%20%3D%20121)
The level of significance,
= 0.95
or,
![(1-\alpha) = 0.95](https://tex.z-dn.net/?f=%281-%5Calpha%29%20%3D%200.95)
![\alpha = 1-0.95](https://tex.z-dn.net/?f=%5Calpha%20%3D%201-0.95)
![Z_{\frac{\alpha}{2} } = 1.96](https://tex.z-dn.net/?f=Z_%7B%5Cfrac%7B%5Calpha%7D%7B2%7D%20%7D%20%3D%201.96)
hence,
The margin of error will be:
⇒ ![E = Z_{\frac{\alpha}{2} }(\frac{\sigma}{\sqrt{n} } )](https://tex.z-dn.net/?f=E%20%3D%20Z_%7B%5Cfrac%7B%5Calpha%7D%7B2%7D%20%7D%28%5Cfrac%7B%5Csigma%7D%7B%5Csqrt%7Bn%7D%20%7D%20%29)
By putting the values, we get
![=1.96(\frac{44}{\sqrt{121} } )](https://tex.z-dn.net/?f=%3D1.96%28%5Cfrac%7B44%7D%7B%5Csqrt%7B121%7D%20%7D%20%29)
![=1.96(\frac{44}{11} )](https://tex.z-dn.net/?f=%3D1.96%28%5Cfrac%7B44%7D%7B11%7D%20%29)
![=1.96\times 4](https://tex.z-dn.net/?f=%3D1.96%5Ctimes%204)
