Question:

Consider Example 20 on mineral deposits.
(a) Show that P(0.8 < X < 1,25 < Y < 30) = 0.092.
(b) Show that the iron content has an expected value of 27.36 and a standard deviation of 4.27.
(c) Show that conditional on X = 0.55, the iron content has an expected value of 27.14 and a standard deviation of 4.14.
