Solve. x^2 8x 25 = 0
kykrilka [37]

A florist wants to determine if a new additive helps
Aleks [24]

The statement fourth "No, the flowers were not put into groups first and then randomly assigned the two additives would be correct.

<h3>What is random experiment?</h3>

Any well-defined method that yields an observable outcome that cannot be precisely predicted in advance is referred to as a random experiment. To avoid any ambiguity or surprise, a random experiment must be properly defined.

We have:

Total number of flowers selected  = 20

And puts in each vase with same amount of water.

10 flowers have been assigned to receive the new additive.

The remaining 10 flowers receive the original additive.

Based on the data, this is not a randomized block design for the experiment because the flowers were not put into groups first and then randomly assigned the two additives.

Thus, the statement fourth "No, the flowers were not put into groups first and then randomly assigned the two additives would be correct.
