Answer:
The answer to your question is r = 4 in
Step-by-step explanation:
Data
Volume = 4000 π in³
height = 250 in
radius = ?
Process
1.- Look the formula to calculate the volume of a cylinder
         Volume = πr²h
2.- Solve for r²
          r² = Volume / πh
3.- Substitution
          r² = 4000π / π(250)
4.- Simplification
          r² = 16
          r = √16
5.- Result
          r = 4 in

To find the median of the data set, we must first order them from lowest to highest in increasing order. Let's rearrange them in that way:
{17, 23, 30, 40, 44, 44}
Then we begin by crossing one off from each side, until we get to the middle. However, we see that our middle here is both 30 and 40.
What we do in a case like this is add up the two numbers and divide by 2 (essentially find the mean of the two middlemost numbers). Let's do that now:


So now we know that 
the median of the set of data is 35.
 
        
        
        
The right answer for the question that is being asked and shown above is that: "The southern California study with a margin of error of 4.9%." the study has the smallest margin of error for a 98% confidence interval is that The southern California study with a margin of error of 4.9%.<span>
