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.

Martha has a deck of cards. she has lost some of the cards, and now the deck only contains nine spades, eleven diamonds, eight clubs, and twelve hearts. martha predicts that whenever she draws a card from the deck without looking, she will draw a club one-fifth of the time. which activity would best allow martha to test her prediction? a. randomly draw a card from the box and see if it is a club. b. randomly draw a card. then, continue to draw another card until all eight clubs are drawn. c. randomly draw and replace a card 120 times. then, observe how close to 30 times a club is drawn. d. randomly draw and replace a card 100 times. then, observe how close to 20 times a club is drawn.
