The confidence interval for population mean is given by :-

, where
is the sample proportion, n is the sample size ,
is the critical z-value.
The values needed to calculate a confidence interval at the 99% confidence level are :
Given : Significance level : 
Sample size : n=450
Critical value : 
Sample proportion: 
Now, the 99% confidence level will be :

Hence, the 99% confidence interval is
