Net Exports are calculated by subtracting Imports from Exports. Assume Exports and Imports are independent of one another. If mean exports are $25M with a standard deviation of $3.5M and mean imports are $30M with a standard deviation of $5M, what is the expected value and variance of Net Exports?

Answer choices:

A. E(Xn) = -$5M V(Xn) = 37.25

B. E(Xn) = -$5M V(Xn) = -12.75

C. E(Xn) = -$55M V(Xn) = -12.75

D. E(Xn) = -$55M V(Xn) = 162.56
