dyeing fabrics. Different fabrics respond differently when dyed.

Dyeing fabrics. Different fabrics respond differently when dyed. This matters to clothing manufacturers, who want the color of the fabric to be just right. A researcher dyed fabrics made of cotton and of ramie with the same “procion blue” dye applied in the same way. Then she used a colorimeter to measure the lightness of the color on a scale in which black is 0 and white is 100. Here are the data for 8 pieces of each fabric:17

                               

Is there a significant difference between the fabrics? Which fabric is darker when dyed in this way?
