Problem: Make your own empirical estimate of the probability that a car is parked "head in" (as opposed to "backed in"). Choose a local parking, such a grocery store. Let A be the event that a car is parked head in. Out of n cars examined, let f be the number of cars parked head in. Then P(A) = f(n).
1. Do you feel your sample is large enough to have a reliable empirical probability?
2. If you had chosen a different parking lot (i.e. church, police station, shopping mall, beach, etc.), would you expect the estimate of P(A) to be similar? Explain your reasoning.
3. Next, pick your own estimate of the probability of a different characteristic regarding the vehicles in the parking lot (i.e. blue v. non-blue cars, trucks v. sedan, tinted windows v. non-tinted windows, etc.). Be creative! Repeat the steps above and explain your answers.
