Question
A poll was conducted on a representative sample of
600
adults living in the United States in order to investigate the decline in cable and satellite TV subscriptions. For this sample,
150
adults revealed that they are "cord cutters," (that is, they canceled their cable/satellite TV service and now only use a video streaming service). You want to estimate p, the true proportion of all US adults who are "cord cutters." Complete parts a through e.
d. Give a practical interpretation of the confidence interval from part
c.
(Type integers or decimals rounded to three decimal places as needed. Use ascending order.)
The probability that the true proportion of all US adults who are "cord cutters" is
enter your response here
lies between
enter your response here
and
enter your response here.
We can be
enter your response here%
confident that the true proportion of all US adults who are "cord cutters" lies between
enter your response here
and

of the population of all US adults, the proportion who are "cord cutters" lies between
enter your response here
and
enter your response here.
There is a
enter your response here%
chance that the true proportion of all US adults who are "cord cutters" lies between
enter your response here
and
