Help please will give 5 stars and amazing feedback! TRUE OR FALSE AND WHY??? (a) Suppose that X is normally distributed with mean 0 and variance 1. Then 3. X is normally distributed with mean 0 and variance 9 True False b) The CLT states that, in large enough samples, the sample average is close to the true ex- pected value with very high probability. True False (c) The assumption that E(ui| X) 0 implies that Cov(ui, Xi)0. True False
Please help!! 5 stars please step by steps and ill leave an amazing comment asap (s) Under the standard OLS asumptions, the estimator jbtained from a regression of y, on X, without a constant is consistent ifAo=0 O True O False (h) Suppose that X, N(0,1) and that X,, i-1,..,n are i.id. Then Vn( -0) is well-approximated by a normal distribution

Assuming that the sample is i.i.d. and that large outliers are unlikely, the coefficient has a descriptive interpretation. O True O...
Please give detailed steps. Thank you. 5. Let {X1, X2,..., Xn) denote a random sample of size N from a population d escribed by a random variable X. Let's denote the population mean of X by E(X) - u and its variance by Consider the following four estimators of the population mean μ : 3 (this is an example of an average using only part of the sample the last 3 observations) (this is an example of a weighted average)...
Only 1-4) X, be a random sample from N(4,a ), , and let X and S be sample mean and sample 1. Let variance, respectively. In Order to show that and S are independent, tollow the steps below. and show the joint pdf of X,X3,*, X 1-1) Use the change of variable technique = Nx = x - is (п-1)5? п(т-и? f(E,x,) еxp ov2x 2a2 Use Jacobian for n x n variable transformation 1-2) Use the fact that X~N(u,a n)...
Please help, 5 stars and a great comment right away!!! (g) E(Xi | Y) = 1 implies that Cov(X,K) = 0. True False (h) Suppose that Xi,... , Xio are independent normal random variables with mean 1 and vari- ance l. Then Σί01 Xi is normally distributed with mean 10 and variance 10. True euc False
