A major research study concluded that the mean number of times that adolescents had engaged in vandalism during the previous 12 months was 3.5 times. We believe the true population mean to be less than this. After collecting our own sample of 36 adolescents, we find that the mean number of times they have vandalized property during a 1-year period was X = 2.9 with a standard deviation equal to .7. Perform all of the procedures necessary for conducting a hypothesis test based on our assumption. What do you conclude? Set your alpha level at .05]
