The number of ads per week has varied from one to seven. The store’s sales staff has been track- ing the number of customers who enter the store each week. The number of ads and the number of customers per week for the past 26 weeks were recorded.
a. Determine the sample regression line.
b. Interpret the coefficients.
c. Can the manager infer that the larger the number of ads, the larger the number of customers?
