Question

Consider two digital fuel pumps A and B that could be used in a single gas station. Pump A has a mean effective process time of 4 minutes with squared-coefficient of variation of 0.5. Pump B has a mean effective time of 3 minute with squared-coefficient of variation of 5.

Answer 1

Pump B has a higher variation in process time compared to Pump A.

Step-by-step explanation:

Pump A has a mean effective process time of 4 minutes with a squared-coefficient of variation of 0.5. This means that the standard deviation of Pump A's process time is equal to 0.5 times its mean, which is 0.5 * 4 = 2 minutes. Pump B, on the other hand, has a mean effective time of 3 minutes with a squared-coefficient of variation of 5. Therefore, the standard deviation of Pump B's process time is equal to 5 times its mean, which is 5 * 3 = 15 minutes. So, Pump B has a higher variation in process time compared to Pump A.
