Visit 10 different drug stores in your area. Evaluate each store in terms of its overall image and quality of in-store service using an 11-point rating scale (1 = poor, 11 = excellent). Then analyze the data you have collected as follows:
(a) Plot the overall image (Y-axis) against relative in-store service (X-axis) and interpret this diagram.
(b) Which measure would you use to determine whether there is a relationship between the two variables? Why?
(c) Run a bivariate regression analysis of overall image on in-store service.
(d) Interpret the regression coefficients.
(e) Is the regression relationship significant?
(f.) Interpret the resulting r2.
