Data proving that my dice rolling is not bewitched

My wife has been convinced that I roll a preternatural number of doubles when we play backgammon. So, I’ve been recording the data for the past couple dozen games we played and I can now say, with the full force of statistics that “I am not a witch – I mean, I am not bewitched.” It is true that in these twenty odd games, my average number of doubles per game is about 0.6 higher than hers, but a student’s t test demonstrates that this is well within the predictable averages. (p = 0.27).Image
