ages of both men and women

Ages of couples 2007. The graph shows the ages of both men and women at first marriage (www.census.gov).

 

Clearly, the patterns for men and women are similar. But are the two lines getting closer together? Here’s a timeplot showing the difference in average age (men’s age women’s age) at first marriage, the regression analysis, and the associated residuals plot.

a) What is the correlation between Age Difference and Year?

b) Interpret the slope of this line.

c) Predict the average age difference in 2015.

d) Describe reasons why you might not place much faith in that prediction.
