Dr Aris wants to investigate the effect of operant conditioning on dog obedience. She splits a sample of rescue dogs into two groups. Group A receives a high-value treat (positive reinforcement) every time they successfully perform a 'sit' command on cue. Group B receives no treats or food rewards when they perform the command. Dr Aris records the total number of successful 'sit' responses completed by each dog during a 10-minute test session.
State a fully operationalised directional (one-tailed) hypothesis for Dr Aris's investigation.
