Question

The autocorrelation function of a random process is Rxx(t) = 12 + 3e-, then the mean
value of the process X(t) is
a) 9
b) 12
c) √12
10.
An information source generates letters taken at random among the letters a, b, c, d and e.
We suppose that P(a)=P(b)=P(c)= and P(d)=P(e) Moreover, a data
compression system transforms the letters into binary strings as follows: a = 1,b=01,c=
001,d0001 and e=0000. Let X be the length of a binary string emitted by the data
compression system. Calculate Fx(2") + F(4");

Let X1, ..., Xn be a random sample from N(μ, σ2), where σ2is known.a) Show that Y = (X1 + X2)/2 is an unbiased estimator of μ.b) Find the Cramer-Rao lower bound for the variance of an unbiasedestimator of μ for a general n.c) What is the efficiency of Y in part (a) above?
The germination rate of seeds is defined as the proportion of seeds that, when properly planted and watered, sprout and grow. A certain variety of grass seed usually has a germination rate of 0.80, and a company wants to see if spraying the seeds with a chemical that is known to change germination rates in other species will change the germination rate of this grass species. (a) Suppose the company plans to spray a random sample of 400 seeds and conduct a two-sided test of 0: 0.8Hpusing = 0.05. They determine that the power of this test against the alternative 0.75pis 0.69. Interpret the power of this test.(b) Describe two ways the company can increase the power of the test. What is a disadvantage of each of these ways? (c) The company researchers spray 400 seeds with the chemical and 307 of the seeds germinate. This produces a 95% confidence interval for the proportion of seeds that germinate of (0.726, 0.809). Use this confidence interval to determine whether the test described in…
Suppose that the random variables X1,...,Xn form a random sample of size n from the uniform distribution on the interval [0, 1]. Let Y1 = min{X1,. . .,Xn}, and let Yn = max{X1,...,Xn}. Find E(Y1) and E(Yn).
A random selection of volunteers at a research institute has been exposed to a weak flu virus. After the volunteers began to have flu symptoms, 10 of them were given multivitamin tablets daily that contained 1 gram of vitamin C and 3 grams of various other vitamins and minerals. The remaining 10 volunteers were given tablets containing 4 grams of vitamin C only. For each individual, the length of time taken to recover from the flu was recorded. At the end of the experiment the following data were obtained. Suppose that it is known that the population standard deviation of recovery time from the flu is 1.8 days when treated with multivitamins and that the population standard deviation of recovery time from the flu is 1.5 days when treated with vitamin C tablets. Suppose also that both populations are approximately normally distributed. Construct a 95% confidence interval for the difference −μ1μ2 between the mean recovery time when treated with multivitamins (μ1) and the mean recovery…
