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:

A good sample population should be diverse and representative of the entire city's movie - going population. Sampling from different locations and different times of day increases the likelihood of getting a diverse group. The first three options are limited in terms of location (high school, mall food court, grocery store) and time (lunchtime for the mall, unspecified but limited time for grocery store). Sampling every fifth person walking down the street in several different locations throughout town at different times of day is more likely to capture a diverse cross - section of the population.

Answer:

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