. This graph explores the correlation between the heights of mothers and their grown daughters. A sample of 12 mother and daughter pairs is plotted here, with the mother's height (in inches) on the x-axis and her daughter's height (in inches) on the y-axis. The best-fit regression line is drawn for you. b) d) 62 I O Daughter's Height Mother's Height What would be the best estimate for the correlation coefficient r for this data? Specify your choice: r=1 r=0.85 r=0.25 r= 0 r=0.25 r=0.85 r= 1 Why did you make that choice? What do the scatterplot and the value of r tell you about the relationship between the heights of the mothers and daughters in this sample? Use the best-t regression line to predict the height of a daughter when the mother is 54 inches tall. Explain how you used the scatterplot to find your estimate. There seems to be a fairly strong correlation between the heights of mothers and daughters. Is there any reason to believe there is causation between heights of mothers and daughters? Explain your reasoning
