analysis of marriage ages

Marriage age 2007, again. Based on the analysis of marriage ages since 1975 given in Exercise 13, give a 95% confidence interval for the rate at which the age gap is closing. Explain what your confidence interval means.

 

Exercise 13

 

Marriage age 2007. The scatterplot suggests a decrease in the difference in ages at first marriage for men and women since 1975. We want to examine the regression to see if this decrease is significant.

 

 

 

b) Here are the residuals plot and a histogram of the residuals. Do you think the conditions for inference are satisfied? Explain.

 


c) Test the hypothesis and state your conclusion about the trend in age at first marriage.
