- A projectile is launched at an angle theta with respect to the surface with velocity v0 (deterministic). If the angle of inclination is a uniform random variable in [0, pi/2 ], calculate the distribution function of the variable R defined as the point of impact of the projectile on the ground, measured from the origin. Also calculate your expected valueDefine Testing for cointegration when θ is unknown ?Suppose that the lifetime, X, and brightness, Y, of a light bulb are modeled as continuous random variables. Let their joint pdf be given by:f(x,y)=λ_1λ_2e^{-λ_1x-λ_2y},x,y>0 •Are lifetime and brightness independent?•Are lifetime and brightness uncorrelated?
- Find the moment generating function of the continuous random variable X∼U (a, b).Please give me the all detailsIf X, Y are normally distributed independent random variables, then show that W = 2X - Y is normally distributed. Do not use moment generating function, only use convolution formula.Find kurtosis by using quartile deviation(formula given in picture).
- If a project has an expected time of completion Te of 45 weeks witha standard deviation of 7 weeks, what is the probability of completing it (a) within one year (52 weeks)? (b) within 38 weeks. Please show formula and bell curve of center limit theorem.If a constant c is added to each possible value of a discrete random variable X, then the expected value of X will be shifted by that same constant amount. Prove that statement using an integration operator.calculate the first moment of the beta function using intergration given that alpha =1 and beta = 4
- can you show the proof for this using the moment-generating function (MGF) method , with explanations pleaseF, G, H with bell curveLet Mx, y be the moment generating function of random variables that are not independent of X and Y.
