At a recent scotch-tasting party, 5 faculty members and their (opposite sex) spouses were guzzling it back pretty well. One person quite correctly noticed that the men seemed to be drinking more than the women. If the mean number of drinks had by the men was 7, and that for the women was 5, and the standard deviation for the whole group was 2 drinks, what was the correlation between gender and the number of drinks consumed?
