answer:
minimum = 20 inches
maximum = 49 inches
Step-by-step explanation:
The height data in the question is
10 15 20 25 30 35 40 45 50.
From above we have the classes as:
10-14, 15-19, 20-24, 25-29, 30-34, 35-39, 40-44, 45-49,
The minimum tree height bus from the first class. While the maximum tree height is from the last class.
The first class is 10-14, so the minimum height = 10 inches
The last class is 45-49 so the maximum height inches = 49 inches.
The maximum tree height from the classes I have grouped is 49 inches since 49 is the upper limit from the last class.
The minimum tree height is 10 inches
