Please help! The probability density function of a continuous random variable X is Find the probability density function of Y = X4. Solution Hi, If you like my answer rate me lifesaver first...that way only I can earn points. Thanks F(Y) = P (Y > y) = P (X^4 > y) = P(X > y ^ 0.25) = Fx(y^0.25) dx/ dy = d(y^0.25)/dy = 0.25/y^0.75 f(y) = F\'(Y) = Fx\'(y^0.25) = 30 y^0.5 8 (1 - y^0.25)^2 * dx/dy = 7.5*y^-0.25*(1- y^0.25)^2.

Please reflect on the role of NPV and payback period in evaluating investment alternatives. How does this effect us as investors? Solution When evaluating a project or long term investment of company, it is important to reach right decisions based on the capital budgeting methods. Net Present Value (NPV) For a project with one investment outlay, made initially, the net present value (NPV) is the present value of the future after-tax cash flows minus the investment outlay. Because the NPV is the amount by which the investor\'s wealth increases as a result of the investment, the decision rule for the NPV is as follows: Payback Period The payback period is the number of years required to recover the original investment in a project. The payback is based on cash flows. For example, if you invest $10 million in a project, how long will it be until you recover the full original investment? Payback period methods is simple and easy to understand, however, it has many drawbacks. First, it is a measure of payback and not a measure of profitability. By itself the payback period would be a dangerous criterion for evaluating capital projects. The payback period may also be used as an indicator of project liquidity. A project with a two- year payback may be more liquid than another project with a longer payback. Because it is not economically sound, the payback period has no decision rule like that of the NPV or IRR. If the payback period is being used (perhaps as a measure of liquidity), analysts should also use an NPV or IRR to ensure that their decisions also reflect the profitability of the projects being considered..

Please quickly I\'m taking the exam now. - What are the four reasons or justifications for government interventionin the economy? Describe two in details, providing an example of eash. Solution Govt intervention is required due to following reasons: 1. Establishing equity based society 2. Presence of negative and positive externalities 3. Macro economic instabilities 4. Making Public goods available Detailed Discription: 1. Macro economic stablisation: Present days economic system is subject to fluctuation due to inflation and recession. Recession is matter of worry where the unemployment issue comes to fore. here private system doesn ot work efficienty and cringe from investing in the economic activities. here govt can interven in the system by making huge stimuls package by investing in varied economic activites. The recent recession in the USA is an example of this where the govt released stimulus packages to deal with problem of recession. 2. Public goods: Public goods such as the road and transportation can not be left to the private sector. Private sector is quite unattentative to invest in public goods. These goods have high positive externalites and are not supposed to provide direct benefits. Hence govt must provide these goods..

Please Provide details and I will raterigh. Solution Let |S| = m , an integer, and let |T| = n . We aregiven that m > n. Now function f can map to one or more elements of T. Thebest case for the most number of distinct mappings is when f coversor reaches all elements of T. In this situation, thereare m-n overflow elements in S that map to a previouslymapped element in T (pigeon hole principle). Or restated,there are elements s1 ands2 in S such thatf(s1) = f(s2). If f does not cover T, then there exists some element t1 in Tthat is not reached. So, some other element of T is reachedby one or more elements in S by f. Or, as before, thereexist one or more elements s1, s2 of S where f(s1)=f(s2).

Show that theta is unbiased. The number of connections to a wrong phone number is often modeled by a Poisson distribution. Suppose we need to estimate the parameter lambda of that distribution (the mean number of wrong connections) by observing a sample x1,...,xn of wrong connections on n different days. Assuming that sigma = x1 + ... + xn > 0. find the m.l.e. and MLE of lambda . Prove that the MLE of lambda is unbiased Solution 1)fn=nCr*(p)^(r)*(1-p)^(n-r) 2)at n=r+1 i can give detailed explanatary solution of all but rate me first.

Please provide answer to question 9.2 page 231 of Manufacturing Engineering and Technologhy, Seventh Edition. Solution In a composite there are two constituent materials. They are matrix and the reinforcement fibres. Reinforcements fibres are embedded in the matrix. Fibres are generally of very high strength and stiffness. Matirx transfer the load between the fibres. During tension fibres handle most of the load but during compression matrix plays a major role in supporting the fibre..

Please provide a step by step and explanation. Turner\'s syndrome is a rare chromosomal disorder in which girls have only one X chromosome. The condition affects about 1 in 2000 girls in the United States. About 1 in 10 girls with Turner\'s syndrome suffers from an abnormal narrowing of the aorta. In a group of 4000 girls, what is the probability that no girls are affected with Turner\'s syndrome? That one girl is affected? Two? At least three? In a group of 170 girls affected with Turner\'s syndrome, what is the probability that at least 20 of them suffer from an abnormal narrowing of the aorta?... Solution We want to use Poisson\'s distribution equation for this probability = expected number^actual number* e ^(-expected number)/actual number factorial (a) we would expect 2 out of 4000 so chance that none are affected is 2^0 (e^-2)/0! 0! = 1 2^0 = 1 e^-2 = 0.135335283 So, probability that none of the girls is affected is 0.135 or 13.5 percent One girl 2^1(e^-2)/1! this is twice as much as we had before Probability of one girl being affected = 0.27 or 27% Chance that two girls are affected, this is the expected number, so we are expeting a high probability here chance that two are affected = 2^2(e^-2)/2! = 0.27 or 27% The chance that at least three are affected is the total probability minus the chances that 0, 1, or 2 are affected Chance of three or more = 1 - 0.135 - 0.27 - 0.27 = 0.323323584 So there is a 32% chance that three or more will be affected. (b) now we expect 17 girls would have the narrowing of the aorta (10% of 170 is 17). The question has a typo, but we could use the same equation. I assume you are asking for one girl, two, and at least three. The odds for only one or two girls to have narrowing is very low. 17^1*(e^-17)/1! = 7.03789E-07 are the odds that only one of the 170 girls has the narrowing 17^2*(e^-17)/2! = 5.98221E-06 are the odds that only two of the 170 girls have the narrowing The odds that at least three have the narrowing is one minus the odds that none, one, or two have the narrowing. Odds that zero have it = 17^0*(e^-17)/0! = 4.13994E-08 So the odds that at least three have the narrowing when we expect seventeen to have the narrowing is 1 - 4.13994E-08 - 7.03789E-07 - 5.98221E-06 = 0.999993273 In other words, there is just about 100% chance that at least three will have the narrowing. Again, you have a typo in (b) so you should make sure that you were asked to find this out instead of something else..

Please post your response to the following focus questions: What is the difference between a felony and a misdemeanor? What is the State Solution Misdemeanors are usually crimes that are considere to be not so serious, examples included but not limited: minor drug offense, DUI, minor thefts. Felonies in the other hand are the most serious type of crime and are classified by degrees, the first degree being the most serious one, examples are: murder, rape. grand theft, etc. Reference: http://www.hg.org/ The burden of proof is placed on the State, who must demonstrate that the defendant is guilty before a jury may convict him or her. But in some jurisdiction, the defendant has the burden of establishing the existence of certain facts that give rise to a defense, such as the insanity plea.
