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. He recorded the time required for the bees to emerge and made observations on their behavior. Jack repeated the experiment every hour for five hours. All repetitions were conducted on the same day as the weather conditions changed from cool and humid in the morning to hot and dry in the afternoon.
