I tried to do the exercise by myself the first time, on a second try, I used excel to make the calculation for me. I notice that the difference between the excel result and the manual result is not that different. And the interval in excel is shorter. Why the Excel calculation is different? is it trustworthy?

Yes you may got different result manually because there may be difference in calculation of digits after point. Excel calculation is more accurate and trustworthy because it will precisely give answer according to data we gave and formula we apply.
