Answer:
the 
confidence interval for the population proportion is:
![\left [0.3469, \hspace{0.1cm} 0.4387\right]](https://tex.z-dn.net/?f=%5Cleft%20%5B0.3469%2C%20%5Chspace%7B0.1cm%7D%200.4387%5Cright%5D)
Step-by-step explanation:
To solve this problem, a confidence interval of 
for the population proportion will be calculated.
![$$Sample proportion: $\bar P=0.3928$\\Sample size $n=751$\\Confidence level $(1-\alpha)\times100\%=99\%$\\$\alpha: \alpha=0.01$\\Z values (for a 99\% confidence) $Z_{\alpha/2}=Z_{0.005}=2.5758$\\\\Then, the (1-\alpha) \times 100\%$ confidence interval for the population proportion is given by:\\\\\left [\bar P - Z_{\frac{\alpha}{2}}\sqrt{\frac{\bar P(1- \bar P)}{n}}, \hspace{0.3cm}\bar P + Z_{\frac{\alpha}{2}}\sqrt\frac{\bar P(1- \bar P)}{n} \right ]](https://tex.z-dn.net/?f=%24%24Sample%20proportion%3A%20%24%5Cbar%20P%3D0.3928%24%5C%5CSample%20size%20%24n%3D751%24%5C%5CConfidence%20level%20%24%281-%5Calpha%29%5Ctimes100%5C%25%3D99%5C%25%24%5C%5C%24%5Calpha%3A%20%5Calpha%3D0.01%24%5C%5CZ%20values%20%28for%20a%2099%5C%25%20confidence%29%20%24Z_%7B%5Calpha%2F2%7D%3DZ_%7B0.005%7D%3D2.5758%24%5C%5C%5C%5CThen%2C%20the%20%281-%5Calpha%29%20%5Ctimes%20100%5C%25%24%20confidence%20interval%20for%20the%20population%20proportion%20is%20given%20by%3A%5C%5C%5C%5C%5Cleft%20%5B%5Cbar%20P%20-%20Z_%7B%5Cfrac%7B%5Calpha%7D%7B2%7D%7D%5Csqrt%7B%5Cfrac%7B%5Cbar%20P%281-%20%5Cbar%20P%29%7D%7Bn%7D%7D%2C%20%5Chspace%7B0.3cm%7D%5Cbar%20P%20%2B%20Z_%7B%5Cfrac%7B%5Calpha%7D%7B2%7D%7D%5Csqrt%5Cfrac%7B%5Cbar%20P%281-%20%5Cbar%20P%29%7D%7Bn%7D%20%5Cright%20%5D)
Thus, the confidence interval for the population proportion is:
