Please complete the following in your textbook; since it's Halloween, I'll wait to check these until Wednesday, so you can do them tomorrow if you don't get a chance tonight (you may have other homework tomorrow also):
Page 213: 1, 2, 7
Also, remember that STAMPS are DUE WEDNESDAY! See the blog post below (from Friday) for more info about stamps.
And lastly, 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.
Tomorrow in class we'll start to discuss more about outliers and influential points! See you there!
