I am in an Intro to Stats class, and I need help with this problem:
According to the Pew Research Foundation, based on a random sample of 1,001 adults, a 95% confidence interval for the proportion of adults who would ride in a driverless car is (0.45,0.51).
What is the best interpretation of this confidence interval?
a)We are 95% confident that the population proportion is between 0.45 and 0.51
b)We are 95% confident that the sample proportion is between 0.45 and 0.51.
I am currently leaning towards A since C.I. are population proportion and the professor did not really go in depth over the distinction between the two. I am wondering if there is a case where we would have sample, or is it always proportion?
If you guys could help me with this problem, that would be wonderful. Thanks.
