=> 
=> 
From the question we are told the confidence level is 99% , hence the level of significance is

Generally from the normal distribution table the critical value of 
is
Generally the sample size is mathematically represented as
![n = [\frac{Z_{\frac{\alpha }{2} } * \sigma }{E} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7BZ_%7B%5Cfrac%7B%5Calpha%20%7D%7B2%7D%20%7D%20%2A%20%20%5Csigma%20%7D%7BE%7D%20%5D%20%5E2)
=> ![n = [\frac{ 2.58 * 0.14 }{0.02} ] ^2](https://tex.z-dn.net/?f=n%20%3D%20%5B%5Cfrac%7B%202.58%20%2A%20%200.14%20%7D%7B0.02%7D%20%5D%20%5E2)
