In the scenarios below, describe errors in the experimental designs and how those errors can be corrected. Scenario 5 Perfumes and Bees' Behavior: Jack read that certain perfume esters would agitate bees. Because perfume formulas are secret, he decided to determine whether the unknown Ester X was present in four different perfumes by observing the bee's behavior. He placed four saucers, each containing 10 mL of a different perfume, in a semicircle 3 m from the hive entrance.
