<PRE><B>Question 1079546</B>
 Need help with Margin of Error 
Suppose you are told that a 95% confidence interval for the average price of a gallon of regular gasoline in your state is from $3.26 to $3.94. Use the fact that the confidence interval for the mean is in the form x &amp;#8722; E to x + E to compute the sample mean and the maximal margin of error E. (Round your answers to two decimal places.)
x = $	 
3.60
Correct: Your answer is correct.
----------
Note:: The Confidence Interval is 2*E wide.
------------------------------------------------
E = (3.96-3.26)/2 = 0.68/2 = 0.34
