Kim wants to know how many families in her small neighborhood of 70 homes would participate in a neighborhood sports event. She put all the addresses in a bag and drew a random sample of 35 addresses. She then asked those families if they would participate in the sports event. She found that 15% of the families would participate in the event. She claims that 15% of the neighborhood families would be expected to participate in the sports event. Is this a valid inference? Yes, this is a valid inference because she took a random sample of the neighborhood Yes, this is a valid inference because the 35 families speak for the whole neighborhood No, this is not a valid inference because she asked only 35 families No, this is not a valid inference because she did not take a random sample of the neighborhood

I am thinking that this is the answer: Yes, this is a valid inference because she took a random sample of the neighborhood.

I am not understanding why this would be correct: No, this is not a valid inference because she asked only 35 families

he only took a sample and he is saying that the entire neighborhood will participate when that would mean that he is relying on the sample to answer for the entire neighborhood

@Kpop_fan A is the option I chose, not B @shernandez03 Inferential statistics makes inferences about populations using data drawn from the population. Instead of using the entire population to gather the data, the statistician will collect a sample or samples from the millions of residents and make inferences about the entire population using the sample.
