The three factors are A = type of mail used 3rd class, 1st class), B = type of descriptive brochure (color, black- and-white), and C = offered price ($19.95, $24.95). The mail- ings are made to two groups of 8000 randomly selected customers, with 1000 customers in each group receiving each treatment combination. Each group of customers is considered as a replicate. The response variable is the number of orders placed. The experimental data are shown in Table P6.6. (a) Analyze the data from this experiment. Which factors significantly affect the customer response rate? 6.28 A company markets its products by direct mail. An experiment was conducted to study the effects of three fac- tors on the customer response rate for a particular product.
