Question 10
Original source text (the exact panel preserves diagram labels, tables and choices):
Biology students carried out an experiment to determine if a certain fertilizer
increased the height of plants. The students selected 4 types of plants and
planted 10 seeds of each type. Five seeds of each type were treated with
fertilizer and 5 seeds of each type were not treated with fertilizer. All other
conditions were identical. The students recorded the plant height after 120 days,
as shown in the table.
