=0.642-0.740 = -0.098
Margin of error = 2.33 *0.024 = 0.056
If we consider this , lower limit = -0.098 -0.056 = -0.154
upper limit = -0.098+0.056 = -0.042
If we consider the other way
difference = 0.74-0.642 = 0.098
Then lower limit = 0.098 -0.056 =0.042
upper limit =0.098+0.056 =0.154
I do not know whether they prompt this way or other way.
That is why I am providing both the answers
