Twenty students were asked to take part in a study. Ten students were asked to watch scary movies and write about the events that scared them most (M=45). The other ten students watched neutral movies as a control group and were asked to write about their day (M2= 60). One month later, both groups rated their overall level of depression on a scale from 0= very depressed to 100 = not at all depressed. If = 10.3 and = 15, what is the correct statistical decision if we predict a difference between the scary movie and neutral movie conditions (accept/reject the null)?
