Note: On 11.3.16, you may use R to get regression coefficients, s, and the mean and standard deviation of Weight. Then do the rest by hand. Also, write an interpretive statement for both (a) and (b) so it is clear that you understand the difference between the two.

Wednesday, April 9

Exam 2, in class. Bring a calculator.

Wednesday, April 16

Hand in Weekly # 6, which is this:

1. Prove the results of Theorem 11.3.2 that relate to Beta_0. That is prove part a (normality), part b (unbiasedness), and part c (variance).
2. Read pages 697-699 on "Testing the Equality of Two Slopes." Then figure out how one can take the output from two simple linear regressions in R along with some simple hand calculations to calculate this test for the equality of slopes. Illustrate the method using exercise 11.3.22.
