a) b) c) d) A two-factor analysis of variance is (two way ANOVA with replication) conducted to test the effect that price and advertising have on sales of a particular brand of bottled water. Each week a combination of particular levels of price and advertising are used and the sales amount is recorded. The computer results are shown below.
