Tonight, please complete the following in your textbook--this counts as two homework assignments (Monday and Tuesday HW):
Page 213: 1, 2, 7, 9abcdef
Also, remember that STAMPS are DUE WEDNESDAY! See the blog post below (from Friday) for more info about stamps.
Here are the answers for #2 in your homework since they're not in the back of the book:
2a.) r = - 0.846;
2b.) According to the model, for each additional 1 year that passes, the predicted difference in average age at first marriage decreases by about 0.015756 years.
2c.) Approximately 1.81 years
2d.) I am not too confident in the predicted difference in age at first marriage for 2010 because this is an extrapolation; in our data set the latest year was 2000, and the year 2010 falls beyond that year.
And here is Wednesday's homework if you're interested in getting a head start:
