Hence, by Prob- lem 55 c in Chapter 4 and the remark following it, 2 Z 2 solitions chi-squared with two degrees of freedom. Next, as a function of y, fY Z y z is an N z, 1 density. Chapter 13 Problem Solutions On the right-hand side, the first and third terms go to zero.
Errata for Probability and Random Processes for Electrical and Computer Engineers
What is different in this problem is that X and Y are correlated Gaussian random variables; i. Since the mean is zero, the second moment is also the variance. For example, if the friend takes chips 1 and 2, then from the second table, k has to be 3 or 4 or 5; i.
First, the empty set is countable. By the hint, [Wt1. Thus, X and Y are jointly Gaussian. The sum over j of the right-hand side reduces to h xi. We need to find the density gubndr T.
We show this to be the case. Here we have used the Cauchy—Schwarz inequality and the fact that since Yn con- verges, it is bounded. Soultions make the following definition and apply the hints: Hence, S0 f is real and even.
Without loss of generality, let 1 and 2 correspond to the two defective chips.
Hence, Yn is WSS. Chapter 9 Problem Solutions a We assume zero means to simplify the notation. Suppose that B is countable. For this choice of pn Xn converges almost surely but not in mean to Solutiobs. Next, since the Xk are i. Observe that Xn takes only the values n and zero. To this end put Zi: Let Xi be i.
If we multiply both formulass by IB im. But this implies Xn converges in distribution to X. Let A denote solutoins event that Anne catches no fish, and let B denote the event that Betty catches no fish.
Chapter 4 Problem Solutions 51 Hence, the answer is four times the probability of getting all spades: Then by the gkbner problem, A is countable, contradicting the assumption that A is uncountable.
In order that the first header packet to be received is the 10th packet to arrive, the gibner 9 packets to be received must come from the 96 data packets, the 10th packet must come from the 4 header packets, and the remaining 90 packets can be in any order.
There are k1For arbitrary events Fnlet An be as in the preceding problem. To prove this, we construct a sample space and probability measure and compute the desired conditional probability.
The corresponding confidence interval is [ We must first find fY X y x. Since the mean function does not depend on t, and since the correlation function depends on t1 and t2 only through their difference, Xt is WSS.
See previous problem ghbner for graph. Let L denote the event that the left airbag works properly, and let R denote the event that the right airbag works properly. Hence, Wt is a Markov process.
In general, Xn is a function of X0Z1. The mean of such a pmf is j p. Then E does not belong to A since neither E nor E c the odd integers is a finite set. Denote the arrival times of Nt by T1T2.
It just remains to compute the quantities used in the formulas. Hence, its integral with respect to z is one.
