Therebare three parts, a , b and c . Please show all elementary steps. Thanks ax;tわ 2 Try doien with MAG ss (s
Prove the following properties using the definition of the variance and the covariance: Q1. Operations with expectation and covariances Recall that the variance of randon variable X is defined as Var(X) Ξ E [X-E(X))2], the covariance is Cov(X, ) EX E(X))Y EY) As a hint, we can prove Cov(aX + b, cY)-ac Cov(X, Y) by ac EX -E(X)HY -E(Y)ac Cov(X, Y) In a similar manner, prove the following properties using the definition of the variance and the covariance: (a) Var(X)-Cov(X,...

can someone show the steps on how to complete this problem thanks 22. Suppose that for a normal random variable X, ECx) what is sd(X), the standard deviation of the sample mean? - 10 and Var(X)-5.24. For a sample of size n 250, (a) 0.1448 (b) 0.2448 (c) 0.3448 (d) 0.4448 (e) 0.5448
Solve the probkem. Must show all work for credit. Do not skip any steps. The function A = Age -0.00693% models the amount in pounds of a particular material after it's stored. The variable x represents the number of years since the material was stored. If 600 pounds of the material are stored now, how much time will need to pass for only 198 pounds of this material to remain? TTTT Paragraph 5. E T. Arial 3 (12pt)
