Ashipping 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 = 230 μ2 = 260 μ3 = 150 σ1 = 9 σ2 = 12 σ3 = 7 (a) assuming that x1, x2, x3 are independent, calculate the expected value and variance of the total volume shipped. [hint: volume = 27x1 + 125x2 + 512x3.]

(co 3) the times that customers spend in a book store are normally distributed with a mean of 39.5 minutes and a standard deviation of 9.4 minutes. a random sample of 25 customers has a mean of 36.1 minutes or less. would this outcome be considered unusual, so that the store should reconsider its displays? no, the probability of this outcome at 0.035, would be considered usual, so there is no problem yes, the probability of this outcome at 0.035, would be considered unusual, so the display should be redone no the probability of this outcome at 0.359 would be considered usual, so there is no problem yes, the probability of this outcome at 0.965 would be considered unusual, so the display should be redone
