Suppose Burger King has run a major advertising campaign in the hopes of increasing monthly sales. To investigate the effectiveness of this campaign, Burger King randomly selected six restaurants and recorded the monthly sales before and after the advertising. The following data represents these sales figures in thousands of dollars. Restaurant 1 2 3 4 5 6
After $123 $122 $145 $156 $160 $134
Before $107 $110 $143 $168 $145 $125
Assuming that the sales for both restaurants does not follow the normal probability distribution, perform a hypothesis test to investigate the effectiveness of the advertising campaign using a=0.05
