Suppose X ~ N(56, 10). What is mu?
Solution :
X ~ N(
,
)
So the value of the mu (
)
is 56
1. X ~ N(mu = 3,sigma=10) Y=2X+4 E(Y) = ? 2. X ~ N(mu = 3,sigma=10) Y=2X+4 V(Y) = ? 3. If X and Y are independent then E(XY) =E(X)*E(Y) True or False? 4. If Cov(X,Y) = 0 then X and Y are independent True or False? 5. If Y_1 ~ N( 1, sigma =2) and Y_2 ~ N(-2, sigma^2 = 16) and Y_1 is independent of Y_2. If l = 2Y_1 - 3Y_2 find E(l) 6. If Y_1 ~...
