I need the solution of this question asap 3, Cov(X1, X2) = 2, Cov(X2, X3) = -2, 5. Let Var(x1) = Var(X3) = 2, Var(X2) Cov(X1, X3) = -1. i) Suppose Y1 = X1 - X2. Find Var(Y1). ii) Suppose Y2 = X1 – 2X2 – X3. Find Var(Y2) and Cov(Y1, Y2). Assuming that (X1, X2, X3) are multivariate normal, with mean 0 and covariances as specified above, find the joint density function fyy, y,(91, y2). iii) Suppose Y3 =...
All questions and round to 4 decimals points please. Thank you! The bloodhound is the mascot of John Jay College? Suppose we weigh n-8 randomly selected bloodhounds and get the following weights in pounds 85.6, 91.6, 105.9, 83.1, 102.1, 92.5, 108.8, 81.4 Assume bloodhound weight are normally distributed with unknown mean of μ pounds and an unknown standard deviation of σ pounds. a) Calculate the sample mean for this data. b) Calculate the sample variance for this data.. c) Calculate...
I need this question to be answered ASAP, and I'll give thumbs up and good comments. Q.3 Find the Area of the surface generated when the curve x2 + y2 = 1, where y > 0 is revolved about x-axis.
1. (a) Which of the following is true and which is false? If you think a statement is true, provide a proof. Disprove those you think are false by giving a counterexample (i) A probability density function never exceeds 1 (ii) Suppose X and Y are two random variables defined on the same sample space, such that X > Y. This implies Var[X > Var Y] (ii) Let Z be a standard normal random variate N(0, 1). Then Z and...
