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
