Answer the following questions with TRUE or FALSE, and explain your answer: (c) For n dependent random variables X1 , . . . , Xn , drawn from the same population with mean µx , E[X bar] = µx . (d) If X has a variance of 4 and mean of 2, and a sample mean based on 4 independent Xi was calculated, the probability that X will be larger than 8 is larger than the probability that X bar is larger than 8. ***Note: (Please do not copy answer from Chegg!)
