Research Scenario #3: A study was conducted to determine what factors are related to sale prices of antique clocks at auction. A sample of 32 clocks recently sold at auction were identified, and the age of the clocks (in years), number of bidders on the clocks, and final sale price (in Canadian dollars) of the clocks were recorded. The auctioneer wants to know if age of clock and/or number of bidders is related to the clocks final sale prices. [10 marks total]

Research Scenario #4: An animal trainer wants to train cats to dance in order to fulfill a lifelong dream. They recruit a sample of 200 cats and their owners to participate in a research study aimed at identifying how different types of rewards may be related to success of training cats to dance. The trainer has cat owners offer their cats one of two kinds of rewards while training them to dance, an Affection Reward or a Food Reward. The trainer documents both the type of reward used and whether or not the cat danced after training. They would now like to know if the type of reward used (Affection, Food) was related to whether or not cats were trained to dance (yes, no). [10 marks total]
