The demand for a commodity is given by Q = Bo + B₁P+u, where Q denotes quantity, P denotes price, and u denotes factors other than price that determine demand. Supply for the commodity is given by Q You, where v denotes factors other than price that determine supply. Suppose that u and v both have a mean of zero, have variances o and o2, and are mutually uncorrelated. Solve the two simultaneous equations to show how Q and P depend on u and v.
If X and Y are independent random variables with X~N(2,32) and Y~N(1,42),find P(X<Y). (You need to write out the calculation process and figure out theanswer)
