- A tea‑drinking Canadian friend of yours claims to have a very refined palate. She tells you that she can tell if, in preparing a cup of tea, milk is first added to the cup and then hot tea poured into the cup, or the hot tea is first poured into the cup and then the milk is added. To test her claims, you prepare six cups of tea. Three have the milk added first and the other three the tea first. In a blind taste test, your friend tastes all six cups and is asked to identify the three that had the milk added first. (b) If your friend is just guessing, what is the probability that she correctly identifies the three cups with the milk added first?

- A travel agency is interested in comparing the travel experiences of customers travelling on two airlines: Airline A and Airline B. They do not know the exact route taken by each airline. The travel agency would like to know if there is a difference in the population mean travel time on a direct flight from Saskatoon to Toronto, depending on the airline a traveler chooses to fly. They recruit 10 employees who are asked to fly direct from Saskatoon to Toronto on Airline A. Each employee is asked to record the amount of time spent in the air. The times recorded by the employees are provided below (in hours). The population mean time for Airline B to fly from Saskatoon to Toronto is 3.4 hours.
