An experimental measurement has a result 7.95 +- 0.01, and a predicted value of 8.00.
How many standard deviations is the experimental measurement from the predicted value?
What is the percent uncertainty in the measurement?
What is the percent difference between measured and predicted value (ignore uncertainties in this final calculation)?
