A park ranger is studying the age and health of Black Cherry Trees in his park. Part of his study displayed the histogram below. Heights of Black Cherry Trees 10 co - Frequency 60 65 70 75 80 85 9 Height (feet) Do not worry about the difference between class limits and class boundaries for this example. Just uses classes 60 - 65, 65 - 70, 70 - 75 etc. 1. Construct a grouped frequency distribution for this data including relative, cumulative, and relative cumulative frequency. 2. Draw a frequency polygon for the data. 3. Draw an ogive for the data. Be sure to label the axis and use appropriate scales. If done using paper and pencil please use a ruler to be accurate
