Question: A researcher wishes to investigate the relationship between the height of a mother and the height of her oldest adult daughter. Here is the data for eight pairs of mothers and daughters

Height of mother in inches (X) 63 67 64 68 62 70 66 64

Height of daughter in inches (Y) 66 68 65 69 66 68 65 66

a. What is the correlation coefficient for these pairs of data?

b. What is the equation of the regression line that best fits the data?

c. If a mother had a height of 65 inches, what is the predicted height of her oldest adult daughter?

d. Do you think that the regression line would be a useful predictor for a woman's height, given her mother's height? Why or why not?
