4) (6 points) Use the following information to answer parts (a) and (b). The scatterplot below shows the relationship between the ages of women when they first married and the ages when they had their first child. The correlation coefficient between the values is 0.9315. The regression equation is Age when had first child = 6.404 + .955(Age when married) a) Would it be appropriate to say that the age at which a woman first marries 40 causes her to have her first child after that age? Explain why or why not. 35 Age - IIIst CHIu 30 24 26 28 30 32 34 Age - married b) Can we use the regression equation to predict the age at which a woman has her first child for a woman who first married at the age of 50? Explain why or why not
