Sue wants to know how many families in her small neighborhood of 50 homes would volunteer to at a neighborhood animal shelter. she put all the addresses in a bag and drew a random sample of 25 addresses. she then asked those families if they would volunteer to at the shelter. she found that 18% of the families would volunteer to at the shelter. she claims that 18% of the neighborhood families would be expected to at the animal shelter. is this a valid inference?
a yes, this is a valid inference because the 25 families speak for the whole neighborhood
b yes, this is a valid inference because she took a random sample of the neighborhood
c no, this is not a valid inference because she only asked 25 families
d no, this is not a valid inference because she did not take a random sample of the neighborhood
