9. You are a memory research interested in the effect of emotional arousal on memory. You find some very emotionally arousing pictures (i.e. scenes from car accidents, laughing celebrities, cute cats). You ask people to rate how emotionally arousing the photos are and later you test their memory recall for these pictures. Write out the 4 steps of hypothesis testing to test whether if increasing arousal is associated with better recall (p<0.05). Make sure to write out your results in APA format and show the effect size (r). Also, you wish to plot the relationship between these variables, write a regression equation for predicting memory based on arousal, and draw a regression line to demonstrate this relationship on the scatterplot. 10 points Pictures Arousal Recall E 2 E 41 S E 12 10.
