  3. I agree with Lena, it was a bit tedious and hard to keep track of all the values but excel really helped. The only thing is that my plot did not come out completely linear (probably expected from experimental data) with r^2 of .993. Does this mean that there is a range acceptable for A and B?

  4. Yes there is a range. I get
    A= -56.0 -+ 2.5
    B = 5140 +- 210

    As long as you are within this general region you are good. Any yes excel is a great help!
