A cognitive psychologist conducted an experiment to investigate whether the presence of ambient white noise affects short-term memory recall. One group of participants (Group A) was asked to memorize and recall a list of 25 words in a completely silent room. A second group of participants (Group B) was asked to memorize and recall the same list of 25 words in a room with ambient white noise played at 65 dB.
Write an appropriate directional (one-tailed) hypothesis for this experiment.
