foie gras fois trois

As New Year’s Eve celebrations are getting quite near, newspapers once again focus on related issues, from the shortage of truffles, to the size of champagne bubbles, to the prohibition of foie gras. Today, I noticed an headline in Le Monde about a “huge increase in French people against force-fed geese and ducks: 3% more than last year are opposed to this practice”. Now, looking at the figures, it is based on a survey of 1,032 adults, out of which 47% were against. From a purely statistical perspective, this is not highly significant since

\dfrac{\hat{p}_1-\hat{p_2}}{\sqrt{2\hat{p}(1-\hat{p})/1032}}=1.36

is compatible with the null hypothesis N(0,1) distribution.
