Question

a poll is being taken on wednesday to predict which movie will be the most popular at the citys movie theaters the next weekend: an animated movie, an action movie, or a romantic comedy. which group would best represent a sample population?
every fifth person coming out of the high school.
every fifth person in the malls food court at lunchtime.
every fifth person coming out of the downtown grocery store at different times throughout the day
every fifth person walking down the street in several different locations throughout town at different times of day.

Explanation:

To predict the most popular movie at the city's movie theaters, the sample population should be representative of the city's diverse population. Sampling from a single location (high school, mall's food court, downtown grocery store) at a specific time may not capture the variety of movie - goers. Sampling every fifth person walking down the street in several different locations throughout town at different times of day is more likely to include a diverse range of people (different ages, occupations, etc.) who are potential movie - goers.

Answer:

Every fifth person walking down the street in several different locations throughout town at different times of day.
