Section 2.6: 1 and 2Notes: In Problem 2.8.9, the definition of q is opposite to the definition of q in Problem 2.6.5. Please replace the last sentence in Problem 2.8.9 with the following:
Section 2.7: 2, 7 (state answer for all possible values of k), and 8 (you should be able to do parts (a) and (b), and give your best effort on part (c))
Section 2.8: 1, 5 (show the computations for part (a)), 7, 9 (hint: find Var[X] and use problem 2.8.7), and extra credit if you solve 10
Section 2.9: Read the text, and solve problem 2.9.6
"How small must the error probability q be to ensure that the jitter is less than 2 milliseconds?"Also, define the jitter as the standard deviation of the random variable T in Problem 2.6.5.
Here is a minor clarification for Problem 2.9.6, part (b). The conditioning event N >= 20 is equivalent to having 19 consecutive tests without a failure. (The problem states 20 consecutive tests without a failure.)
