Question

Data was collected for 40 randomly selected trees growing in the median strip of a busy freeway. The height of each tree (in inches) was recorded. Data was recorded to the nearest whole inch. The data is summarized in the histogram below.
2 4 6 8 10 height (in) 10 15 20 25 30 35 40 45 50 Frequency
What is the maximum possible tree height for the data recorded for this histogram? Note: Each class contains its lower class boundary, but not its upper class boundary.
Minimum tree height = inches Maximum tree height = inches

Answer 1

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
