I highly doubt this is the case. This gives a min slope of 3.0 and a max of 3.2 for an uncertainty of +/- 0.1. How does one estimate the error range for a parameter obtained from the slope of a line of best fit on a set of (x,y) data? Any clarifying points you can provide would be much appreciated.
