2. perform 2-way anova with replication
To answer these questions, an experiment was designedusing laundry detergent pods. For ten weeks, 160 subjects receivedinformation about the products. The factors under considerationwere the number of promotions (1, 3, 5, or 7) that were describedduring this ten†week period and the percent that the product wasdiscounted (10%, 20%, 30%, or 40%) off the average nonâ€promotionalprice.
