I'd say 980.....1404 x .31 is about 435 Subtract that from 1404
0 is the answer to the question.
<span>Lets calculate an example:
Say, .001% of tires that come from the factory are bad. There is a 1/1000 chance that for any given tire randomly selected from the warehouse that a defect will be present. Each tire is a mutually exclusive independently occurring event in this case. The probability that a single tire will be good or bad, does not depend on how many tires are shipped in proportion to this known .001% (or 1/1000) defect rate.
To get the probability in a case like this, that all tires are good in a shipment of 100, with a factory defect rate of .001%, first divide 999/1000. We know that .999% of tires are good. Since 1/1000 is bad, 999/1000 are good. Now, multiply .999 x .999 x .999..etc until you account for every tire in the group of 100 shipped. (.999 to the hundredth power)
This gives us 0.90479214711 which rounds to about .90. or a 90% probability.
So for this example, in a shipment of 100 tires, with a .001% factory defect rate, the probability is about 90 percent that all tires will be good.
Remember, the tires are mutually exclusive and independent of each other when using something like a factory defect rate to calculate the probability that a shipment will be good.</span>

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
