9. A botanist wants to determine if environmental temperature affects root growth. In her
experiment, she creates 4 rooms at temperatures that vary by 5 degrees F. Each room
gets 20 seedlings of the same species, which she grows on agar plates for 60 days.
Once a day, she measures the length of each seedling's root. At the end of 60 days,
she compares the length of the roots with the room temperature. She finds the room
with the lowest temperature produced the longest roots.
