Question #8-12Question #8-12 A scientist was conducting an A scientist was conducting an

experiment on whether plants grew experiment on whether plants grew better with fertilizer added to the better with fertilizer added to the soil. She set up 20 plants of the soil. She set up 20 plants of the same type in the window and added same type in the window and added fertilizer to 10 of them. She then fertilizer to 10 of them.
