A shipping company handles containers in three different sizes:
(1) 27 ft3 (3 × 3 × 3), (2) 125 ft3, and (3)
512 ft3. Let Xi (i
= 1, 2, 3) denote the number of type i containers shipped
during a given week. With μi = E(Xi) and
σi2 = V(Xi), suppose
that the mean values and standard deviations are as follows:
μ1 = 210
μ2 = 260
μ3 = 130
σ1 = 11
σ2 = 12
σ3 = 7
