- HW 10, due 12/6 (Solution)
Chapter 6: 7, 9, 10, 11, 22, 24, 26, 28, R1, R5, R10 - HW 9, due 11/29 (Solution)
Chapter 5: 62, 65, 66, 67, 71, 76, R9
Chapter 6: 3, 4, 5
Notes:
On 62, the regression function of X on Y is E(X|Y).
On 67, use geometry, not calculus (unless you really want to...)
On 76, there is an error!, should have p/2 instead of 1/2, so is 1-p+(p/2)(e^t+e^-t).
Finally, the integral of xe^(-ax) for x between 0 and infinity is 1/a^2. You can either use this result or do it yourself, either by integration by parts or by realizing it's only a constant away from being the expected value of an exponential random variable. - Suggested Problems, not to be collected
