Is there a good reason to believe that evening customers purchase, on average, more than day customers? Support your answer by performing a statistical test on the difference between the mean day purchase and the mean evening purchase (using a one-tailed test). PLEASE JUST HELP DRAW ONE TAILED TEST WITH EXPLANATION. THANK YOU
