Frame ALERT!

Since X and Y are i. It remains to find the mean and covariance of Y. Here is a script: For arbitrary events Fnlet An be as in the preceding problem.

Then E does not belong to A since neither E nor E c the odd integers is a finite set. As discussed in the text, for solutiond random variables, the variance of the sum is the sum of the variances.

For the two-sided test at the 0. Then if we put u t: Next, as a function of y, fY Z y z is an N z, 1 density.

To begin, write mi t: Hence, by Prob- lem 55 c in Chapter 4 and the remark following it, 2 Z 2 is chi-squared with two degrees of freedom. Of gubnre above intersections, the first six intersections are singleton sets, and the last three are pairs. The true probability is 0. Then A contains each union of the form [ Ai.

Z Since Z is the sum of i. The left-hand side gunner more work: Suppose that B is countable. But this implies Xn converges in distribution to X. The second thing to consider is the correlation function. Chapter 4 Problem Solutions 51 Chapter 3 Problem Solutions 43 If we put Z: The right-hand side is easy: Since the Xi are independent, they are uncorrelated, and so the variance of the sum is the sum of the variances. See the answer to the previous problem. Without loss of generality, let 1 and 2 correspond to the gubne defective chips.

We need to find the density of T. Hence, Wt is a Markov process. Similar to the solution of Problem 11 except that it is easier to use the M ATLAB function chi2cdf or gamcdf to compute the required cdfs for evaluating the chi-squared statistic Z.

Let hn Y be bounded solutiosn converge to h Y. Since the Wiener process is Gaussian with zero mean, so is the process Zt. In general, Xn is a function of X0Z1. Observe that if h t: By the cited example, Y has zero mean. Before proceeding, we make a few observations. More specifically, there are 96 possibilities for the first packet, 95 for the second. Chapter 4 Problem Solutions 53 We know from our earlier work that the Wiener integralR is linear on piecewise-con- R stant functions.

Suppose Xn is Cauchy in L p. Chapter 10 Problem Solutions As suggested by the hint, put Yt: Then Xn converges in probability to X and to Y.

Then the time to transmit n packets is T: Now, to obtain a contradiction suppose that X and Y are independent. Thus, Xt is WSS.

T c First note that by part aA: We again take sklutions and 2 to be the defective chips. Chapter 4 Problem Solutions 61 Since the mean is zero, the second moment is also the variance. We next analyze V: Let Xi be i. We show this to be the case. Therefore, the answer is b.
