Question
Transcribed Image Text: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.
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.
