A random selection of 300 people is surveyed in order to try and discover what is the favorite grocery store to shop at in their town. If 150 people say that they prefer to shop at the north side grocery store, 74 people say they prefer the south side grocery store, and 76 people say they prefer the east side grocery store, is it safe to assume that more people prefer the east side store over the south side store if the total population of the city is 80,000 people? Choose the best answer.
- Yes. A random sample will always yield accurate results.
- No. A second sample may show that the south store is preferred.
- Yes. The sample represents the population exactly.
- No. The south side store has better hot dogs.
