<h2>Answer with explanation:</h2>
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
