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
its "C" the third one
ok thank you
your welcome can i have medal
ok then any one else agree
plz just click best response
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
ok idk im going to with c and if thats not correct then im going with b and giving a medal to the one who is right
@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.
