Help with this please

6. You are the quality control inspector at a milk bottling plant in the US that produces both small (1 cup) and large (1 gallon = 16 cups) containers of milk. You take a sample of each product and observe that the mean volume of the small containers is 1 cup with a standard deviation of 0.25 cups, and the mean volume of large containers is 1 gallon with a standard deviation of 0.5 cups. Which of these two products is having the greater issue with quality (variation in volume is a sign of something wrong on the production line)
