1. You are thinking of taking a family trip to Old Orchard Beach in Maine and are hoping to do some swimming. You ask a few acquaintances who have been about the water temperature and they all say it is very cold. From this you conclude that most people including yourself and family would find the water very cold.
   1. Who is the population of interest?
   2. Who is the population that was sampled from?
   3. What if any are the differences between the population of interest and the population that was sampled from that might affect the results?
   4. Would these results generalize to the population of interest (Would the study have external validity)?
