Ad recall In Exercises 27 and 29, we see the number of advertised brand names people recalled immediately after watching TV shows and 24 hours later. Strangely enough, it appears that they remembered more about the ads the next day. Should we conclude this is true in general about peoples memory of TV ads? a) Suppose one analyst conducts a two-sample hypothesis test to see if memory of brands advertised during violent TV shows is higher 24 hours later. If his P- value is 0.00013, what might he conclude? b) Explain why his procedure was inappropriate. Which of the assumptions for inference was violated? c) How might the design of this experiment have tainted the results? d) Suggest a design that could compare immediate brandname recall with recall one day later.
