An arcade's owners are considering extending the hours of the week that it is
opened. The owners would like to survey 150 randomly selected families to see
whether extended hours would be of interest to those that may visit the arcade.
What is the best way to randomly choose these 150 families?
Ask the first 150 families that enter the arcade on a busy Saturday.
Have the owners of the arcade ask the first 100 people they see.
Allow a random number generator to come up with 150 families within a 30 mile
radius of the arcade.
Choose a neighborhood near the arcade and ask 100 families in this
neighborhood.
