Plz 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?
a. yes, this is a valid inference because she took a random sample of the neighborhood
b. yes, this is a valid inference because the 35 families speak for the whole neighborhood
c. no, this is not a valid inference because she asked only 35 families
d. no, this is not a valid inference because she did not take a random sample of the neighborhood
