My research tests the hypothesis that brunettes are less likely than redheads to be left-handed. I get the following observations:Brunette lefties: 5Brunette righties: 104Redhead lefties: 7Redhead righties: 106From this, can I conclude, for the purposes of research, that hair color and being left-handed are associated?-Yes; the proportion of redheads who are lefties is greater than the proportion of brunettes-No; the difference might be due to random error-No; all brunettes would need to be left-handed-No association because this doesn't make sense
