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.**Histogram Explanation:**- The x-axis represents the tree height in inches, ranging from 30 to 70.- The y-axis represents the frequency, ranging from 0 to 12.- The histogram contains the following bars: - 30 to 35 inches: Frequency of 2 - 35 to 40 inches: Frequency of 3 - 40 to 45 inches: Frequency of 6 - 45 to 50 inches: Frequency of 10 - 50 to 55 inches: Frequency of 12 - 55 to 60 inches: Frequency of 5 - 60 to 65 inches: Frequency of 2 - 65 to 70 inches: Frequency of 0**Question:**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.Maximum = [Provide Answer Here]
