Questions: A sample must be a fair and accurate representation of the population to make valid inferences. True False

The answer is True: A sample must be a fair and accurate representation of the population to make valid inferences.

Explanation:

• For statistical inferences to be valid, the sample from which data is drawn must accurately reflect the characteristics of the entire population. This ensures that the conclusions drawn from the sample can be generalized to the population as a whole.
• If the sample is biased or not representative, any inferences made could be misleading or incorrect. For example, if a survey about dietary habits only includes responses from a specific age group, it may not accurately represent the dietary habits of the entire population.
• Ensuring a fair and accurate representation often involves using random sampling techniques and considering factors such as sample size and diversity within the population.
