 Compare fbest and facc with the overall error, which gives the range, as discussed in class. Does the accepted value of f fall within the range centered at the best value? Hint: Check if fmin < facc < fmax, where fmin is the minimum possible using the values of the uncertainty and plugging into the formula by subtracting the uncertainty in the numerator and adding the uncertainty in the denominator; similar reverse logic should be used to get fmax: add in the numerator and subtract in the denominator.
