Christina obtained the following results for about 500 families: Average weight of husband = 170 lbs, SD=10 lbs Average weight of wife=140 lbs, SD=5 lbs • Correlation r=0.4 The scatterplot of the dataset shows the relationship between husbands and wives weights is linear. Of the women who were married to men of weight 200 lbs, their estimated average weight will be (A) 200 (B) 200+0.4* (140-170) (C) 140+ 0.4*10 (200-140) (D) 140+0405 (200-170)
