Question

the national proportion of all households in the united states that turn out the lights and pretend not to be home on Halloween is 0.28. is 0.28 in the confidence interval you computed? based on your answer does it see that the Cherry Creek neighborhood is much different (either higher or lower proportion) from the population of all US households? explain

Answer 1

Err....You'll need to tell us the "confidence interval you computed". We can't compute that with the info you've provided here

Answer 2

its 0.28 or 28%

Answer 3

How are we supposed to tell you if 28% is in your confidence interval if you haven't given us the confidence interval?
