A student wonders if tall women tend to date taller men than do short women. She measured herself, her dormitory roommate, and the women in the adjoining rooms; then she measured the next man each woman dates. Here are the data (heights in inches): Women (x) Men (y) 66 72 64 68 66 70 65 68 70 71 65 65 a. Make a scatterplot of these data. Based on the scatterplot, do you expect the correlation to be positive or negative? Near 1 or not? b. Find the correlation, r, between the heights of the men and women. c. How would r change if all the men were 6 inches shorter than the heights given in the table? Does the correlation tell us whether women tend to date men taller than themselves? d.If heights were measured in centimeters rather than inches, how would the correlation change? (There are 2.54 centimeters in an inch.) e. If every woman dated a man exactly 3 inches taller than herself, what would be the correlation between male and female heights?
