A mall is interested in comparing two coffee shops and customer satisfaction. They compare guests at the first coffee shop (n=70) and the second coffee shop(n=73). Our data is coded so that a higher score indicates higher customer satisfaction.

They find the sample mean for coffee shop 1 (###!) to be 7 and the sample mean for coffee shop 2 to be (###") 8. They then find the sum of squares value for Tokyo (!) to be 300 and London (")to be 323. Will the mall reject or fail to reject the null?
