Q. Maya surveyed 1717 passengers on a city bus.\newlineIs this a random sample of the inhabitants of the city?\newlineChoices:\newline(A)yes\newline(B)no
  1. Random Sample Definition: Question Prompt: Is the sample of 1717 passengers on a city bus a random sample of the inhabitants of the city?
  2. Scenario Analysis: Step 11: Understand the concept of a random sample. A random sample means every individual in the population has an equal chance of being selected.
  3. Sample vs Population Comparison: Step 22: Analyze the scenario. Maya surveyed only 1717 passengers on a city bus. This group is likely not representative of the entire city's population, as it only includes bus passengers at a specific time and place.
  4. Sample vs Population Comparison: Step 22: Analyze the scenario. Maya surveyed only 1717 passengers on a city bus. This group is likely not representative of the entire city's population, as it only includes bus passengers at a specific time and place. Step 33: Compare the sample to the population. Since the sample consists solely of bus passengers, it may not include people who use other forms of transportation or none at all. This could bias the results as it doesn't cover all demographics.
