Homework 4, ECE302, Spring 2013, Prof. Boutin
Due in class, Wednesday February 20, 2013.
As usual, homework 4 consists in handing in the solutions of the exercises that were assigned after each lecture.
Hand in a hard copy of your solutions in class. Make sure to include a cover page and to staple all the pages together. Write legibly and clearly. Put the problems in order. Do not write on the back of the pages. Do not use paper torn out of a spiral book. Thank you very much.

- On the third set of problems, do you mean 3.65 instead of 5.65? Also, on the fourth set, is it 3.1 or 3.91? I just want to ensure it is not a typo before I do the problem. Thanks! Aboldt 15:57, 17 February 2013 (UTC)
- Thank you. - TA
- On question 16 and 27, how do you deal with a infinite discrete random variable x? How do you calculate the probabilities with only known expected value?
- Can you please clarify your question about the infinite discrete random varieble x? Regarding the calculation of probabilities when only the expected value is known, note that it is generally impossible to derive the pmf of a random variable only from its expected value. However, there is something remarkable about the mass on the left side of the mean and the mass on the right side of the mean: they must be equal! Do you know why? -pm
