Group Radii of Tomatoes (centimeters)
Fertilized 0.8, 1.1, 0.9, 0.8, 1.0, 1.2, 0.9, 1.1, 1.0, 1.2
Unfertilized 1.4, 1.6, 1.3, 1.5, 1.1, 1.5, 1.6, 1.2

Todd randomly divided some tomato plants into two groups. He applied fertilizer to one group, but did not apply fertilizer to the other group. Then he measured the radii of the tomatoes produced by the plants in each group. His data is shown in the table.

What is the difference in the mean radius of the tomatoes from the fertilized plants and the mean radius of the tomatoes from the unfertilized plants?
A) 0.3 centimeters
B) 0.4 cent
