-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?
A)Yes, we can always make predictions once we have a regression equation.
B)Yes, we can make a prediction because the scatterplot shows a strong positive linear relationship.
