You and your friend are enrolled in two different sections of the Algebra, Functions, and Data Analysis course. Recently, different midterm tests were given in each section. Since the high school has large class sizes, the test scores in both sections are approximately normally distributed. In your section, the mean was 80 and your score was 92. In your friend's section, the mean was 71 and her score was 83. Is it possible to determine who did better?
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)
