Answer:      Margin of Error = 1.944
                     Lower Bound = 3.052
Explanation:- 
Attached below is a file for monthly Rate of return. Used an excel sheet to determine the confidence interval which seems relatively easier as compared to manual computation. The range below (A2:A40) shows the monthly 
Functions used : Standard Deviation as= STDEV (A2:A40) 
                              Sample Mean	= AVERAGE(A2:A40)
                              Margin of Error = CONFIDENCE.T(D4,D5,D2)
                               Lower Bound Interval = D6-D7 = -3.052

There are 4 cups in a quart.
There are 12 cups in x quarts.
Solution
4/12 = 1 / x                               Cross multiply
4x = 12*1                                  Combine
4x = 12                                     Divide both sides by 4
4x/4 = 12/4
x = 3 quarts
Answer
