Answer to Problem 21PPS
An experiment
Explanation of Solution
Given information :
A situation, "You want to test a treatment that keeps deer out of your garden."
Calculation :
An experiment because gardens with deer is random test group. And gardens are population.
Half the gardens with deer will be given the treatment and half of given is placebos, gardens with treatment are treatment group and those give the placebo are the control.
