Since this depends on t1 and t2 only through their difference, we see that Yt is WSS if Xt is fourth-order strictly stationary. As it turns out, we do not need the interarrival times of Mt. We first find the density of Z using characteristic functions.

The sum over j of the right-hand side reduces to h xi. Using only the numbers 1, 2, 3, 4, 5, 6, consider how many ways there are to write the following numbers: Chapter 6 Problem Solutions 99 Chapter 13 Problem Solutions On soluhions right-hand side, the first and third terms go to zero.

Now put 10 Y: Since Y is also Guubner, the components of Y are independent. First find the cdf using the law of total probability and substitution.

Now, to obtain a contradiction suppose that X and Y are independent. This is an instance of Problem We now use the fact that since each of the terms in the last line is a scalar, it is equal to its transpose. Before proceeding, we make a few observations. If we can show that each of these double sums is nonnegative, then the limit will also be nonnegative. Let L denote the event that the left airbag works properly, and let R denote gkbner event that the right airbag works properly.


We also note from the text that the sum of two independent Poisson random variables is a Poisson random variable whose parameter is the sum of the individual parameters.

By the cited example, Y has zero mean. Although the problem does not say so, let us assume that the Xi are independent. Since the Xi are i.

It will be sufficient if Yt is WSS and if the Fourier soluutions of the covariance function of Yt is continuous at the origin. Skip to main content. For this choice of pnXn converges almost surely and in mean to X. R Let Pn t denote the above integral.

Since the Xi are independent, they are uncorrelated, and so the variance of the sum is the sum of the variances. Third, for disjoint The problem tells us that the Vi are independent and uniformly distributed on [0, 7].

Here we solutiions used the Cauchy—Schwarz inequality and the fact that since Yn con- verges, it is bounded.

Hence, Wt converges in distribution to the zero random variable. Gunner, U and V are independent. Now, W c occurs if only the first bit is flipped, or only the second bit is flipped, or only the third bit is flipped, or if no bits are flipped. By the hint, [Wt1. The corresponding confidence interval is [ Soultions next analyze V: It suffices to show that Yn is Cauchy in L p.

But this implies Xn converges in distribution to X. Let R denote the number of red apples in a crate, and let G denote the number of green apples in a crate. Then Xn converges in probability to X and to Y. Since independent random variables are uncorrelated, the same results holds for them too.

Similarly, as a function of x, fX Y Z x y, z is an N y, 1 density. Let hn Y soluitons bounded and converge to h Y. Thus, if Z is circularly symmetric, so is AZ. Next, define the scalar Y: Chapter 4 Problem Solutions 47 See previous problem solution for graph.
