4. For the two circumstances below, explain which type of probability (empirical, subjective, theoretical) is being used to make the prediction. If more than one type of probability is involved, explain which elements of the process use which of the methods. a. A scientist studying ants builds an ant farm and maps the routes they travel throughout the course of a week through careful observation. Later the scientist uses these observations to generate an interactive map of a natural environment that lists the probability of finding ants in any given location at a particular time. b. A social scientist studying grocery store accessibility in a city recruits a small sample of study volunteers and interviews them about how far they travel for groceries. The researcher finds in the study that people from higher-income neighborhoods travel significantly less than people from low-income neighborhoods. Using a statistical model, the researcher predicts that their sample has a 95% chance of being a good reflection of the population, meaning that the results of her study are reliable.
