These will be the more useful version of the graphs. • Percentages (i.e. relative frequencies) are more useful than counts (i.e. frequencies) • Half (49.2%) of the Retailer Visits are to the Dealer Locator page. REI Online and Zappos are the two most frequently visited retailer. • More than half (54.3%) used Google and almost one- quarter (23.8%)used Direct as a Search Engine. • 84.3% of the visits were from the United States and another 5.3% from Canada; that accounts for about 90% of the total visits and provides the obvious focus of advertising. 5 Question 4 – Delivery Service (from the text: Chapter 4, page 83, # 42) a) Pack Rats has delivered a total of 28 late packages (12 Regular + 16 Overnight), out of a total of 500 deliveries (400 Regular + 100 Overnight).
