A survey by a research company reported that 40% of retired people eat out at least once a week. You run a restaurant, and you are wondering if you should focus more of your advertising on retired people. However, you are concerned that the research might not apply to your city. You decide to check on the research results. You hire a statistics student to conduct a random sample of 150 retired people in your city. The student reports that 44 of them eat out at least once a week. Do these sample results suggest that the percentage of retired people who eat out at least once a week in your city is less than in the research study? Is there anything else you should consider?
