In a neuroscience research lab, the researchers want to know the effects of long-term marijuana use on memory and reaction times. In order to investigate their research hypothesis a sample of 50 long-term marijuana users between the ages of 35-45 were selected with a mean memory and reaction time of 69.4 seconds. The population average for the same age group has a mean of 48 and S.E.M. is 7. Go through the steps of hypothesis testing, select appropriate statistics and state your results, use a=.05.
