, 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

<u>Answer</u>
A. c = 4
<u>Explanation</u>
In algebra, what you do to one side of the equation, the same has to be done on the other side.
32c = 128
divide both sides by 32
32c = 128.
32c ÷ 32 = 128 ÷ 32
c = 128/32
= 4
