3. Landscapers are growing two groups of oak tree saplings in a greenhouse before transplanting them
outside. The trees were all germinated at the same
time. One group of saplings was fed the standard
treatment of fertilizer and food, while a second group
of saplings was given a new treatment. After several
months, the height in inches of each sapling was
measured and recorded. The results are provided in
the table to the right.
How does the standard deviation for the height of the
new treatment compare to the standard deviation of
the old treatment? Round values to two decimal places.
