2. A researcher is interested in the relationship between arousal and memory recall. Arousal will be manipulated by giving participants an injection of adrenaline at doses of 0 (control), 1, 5 or 10 mg/kg. Ten participants are randomly assigned to each dose group. Immediately after injection subjects are shown a list of 50 words to remember. The next day the participants return to the lab where they are given a free recall test. The number of words correctly recalled were recorded. Based on the results shown below, what can you conclude about the effects of arousal on memory? Set a = .05. 0 M = 21.8 a. State hypotheses: Dose of adrenaline (mg/kg) 1 5 M = 19.2 M = 31.2 b. Set criterion for making a decision about Ho: 10 M = 18.6
