Mathematics
A soft-drink dispensing machine is said to be out of control if the variance of the contents exceeds 1.15 deciliters. If a random sample of 25 drinks from this machine has a variance of 2.03 deciliters, does this indicate at the 0.05 level of significance that the machine is out of control? Assume that the contents are approximately normally distributed.

Ответ:
48.125 ft³
Step-by-step explanation:
The space occupied by the new generator is the product of it's dimension:
The space occupied = Length * width * height
Space occupied = 3 1/2 * 5 1/2 * 2 1/2
Space occupied = 7/2 * 11/2 * 5/2
Space occupied = (7*11*5) / (2*2*2) = 385 / 8
Space occupied = 48.125 ft³
