Given,
Mean is,
Standard deviation,
,
Margin of error(E) = 0.54,
For 98% level of confidence, 
Thus, the sample size would be,
![n=[\frac{z_{\frac{\alpha}{2}}\times \sigma}{E}]^2](https://tex.z-dn.net/?f=n%3D%5B%5Cfrac%7Bz_%7B%5Cfrac%7B%5Calpha%7D%7B2%7D%7D%5Ctimes%20%5Csigma%7D%7BE%7D%5D%5E2)
![=[\frac{2.33\times 8.8}{0.54}]^2](https://tex.z-dn.net/?f=%3D%5B%5Cfrac%7B2.33%5Ctimes%208.8%7D%7B0.54%7D%5D%5E2)
