Answer:
b) True , this is right. But this is not for 1000 alone for any sample size of large number randomly drawn we can expect 95%
Step-by-step explanation:
Given that in 2013, the Pew Research Foundation reported that "45% of U.S. adults report that they live with one or more chronic conditions", and the standard error for this estimate is 1.2%
Let us check one by one answers given
a) False. Because we can say 95% or 90% confident only that the true percent of US adults cannot be true.
b) True , this is right. But this is not for 1000 alone for any sample size of large number randomly drawn we can expect 95%
c) False this does not give whether less than 50% or not unless we know the confidence interval range.
d) False, std error is a measure of variation of all the items from the mean.
The answer is C, good luck!
