1.

perform Levene’s test for equal variance. Note, this is aone‐way ANOVA testing for the equality of 16 variances (eachcombination of promotion/discount). 0.1 signigicance

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 non‐promotionalprice. Ten individuals were randomly assigned to each of thesixteen combinations. The data reflecting what the sub‐ jects wouldexpect to pay for the product (i.e., their reference price) at theend of the 10‐week period. 0.1 significance
