Question 1191261: A student was asked to find a 99% confidence interval for the proportion of students who take notes using data from a random sample of size n = 70. Which of the following is a correct interpretation of the interval 0.1 < p < 0.3?
Check all that are correct.
With 99% confidence, a randomly selected student takes notes in a proportion of their classes that is between 0.1 and 0.3.
There is a 99% chance that the proportion of the population is between 0.1 and 0.3.
There is a 99% chance that the proportion of notetakers in a sample of 70 students will be between 0.1 and 0.3.
The proportion of all students who take notes is between 0.1 and 0.3, 99% of the time.
With 99% confidence, the proportion of all students who take notes is between 0.1 and 0.3.

You can put this solution on YOUR website! The last one is by far the best interpretation.
CI are about parameters, not samples. The value in the sample you know. We don't use "chance" but rather confidence.
The first one uses confidence, but a randomly selected student either does or doesn't take notes and that is a dichotomous 0/1 probability, not an interval.
