Is this a randomized block design for this experiment?
O Yes, each flower is randomly assigned to the
treatments.
A
A florist wants to determine if a new additive helps
extend the life of cut flowers longer than the original
additive does. The florist selects 20 flowers of different
types and puts each flower in its own vase with the
same amount of water. She positions the vases so they
also receive the same exposure to light. She numbers
the flowers 1-20, and places these numbers on equal-
sized slips of paper. The slips are placed in a hat and
mixed thoroughly. A slip is chosen and the corresponding
flower receives the new additive. After the hat is shaken,
another slip is chosen and the corresponding flower also
receives the new additive. This procedure continues until
10 flowers have been assigned to receive the new
additive. The remaining 10 flowers receive the original
additive.
O Yes, the flowers were placed in their own vases, and
received the same amount of water and light.
O No, only 20 flowers were used in the experiment.
O No, the flowers were not put into groups first and then
randomly assigned the two additives.
