Question:
In July 2013, Gallup surveyed 2,027 randomly selected U.S. adults. They found that of the 921 people who described themselves as overweight, 424 reported having some or many friends/family members who were overweight (424/921 = 0.46). Also, of the 1,106 people who described their weight as being “about right,” 332 reported having some or many friends/family members who were overweight (332/1,106 = 0.30). Use the conditional proportions to explain whether the data indicate that there is an association between whether one perceives oneself as being overweight and whether they have some or many friends/ family members whom they perceive as being overweight.
